Available in PDF, EPUB and Kindle. Book excerpt: Many resources have been devoted to developing novel catalytic systems in efforts to improve the activity of electrochemical reactions while more efficiently utilizing the precious metal catalyst. However, in order for these catalyst systems to be relevant industrially they must be in the form of particles. Conventional synthesis methods are too simplistic for these systems, which require a higher level of control in their synthesis. Atomic layer deposition (ALD) was used to deposit Pt layers on tungsten monocarbide (WC) particles in an effort to produce monolayer Pt-WC catalysts. DFT calculations predicted that one monolayer of Pt on a WC substrate should perform as well as a Pt catalyst for the ORR. Pt ALD was first demonstrated on WC thin films and the growth and nucleation characteristics were studied. A nucleation period was observed where the growth per cycle was quite slow; after which the growth rate increased considerably. When few ALD cycles were used, Pt particles were well dispersed on the WC surface, but eventually with increased ALD cycles, merged to form a continuous layer. Pt monolayer growth is difficult on WC because there are few available adsorption sites for the Pt precursor, and discrete Pt particles are created instead. With increasing ALD cycles, existing Pt particles are more likely to grow rather than nucleate elsewhere on the WC surface. Therefore, in order to make thinner Pt layers the nucleation density must be increased at low ALD cycles. Pt ALD was then applied to WC powders to compare growth characteristics with the thin films. TEM imaging and Cu stripping voltammetry found that Pt ALD growth on the WC powder substrate was similar to that on WC thin films. However, the presence of excess free carbon was found to affect Pt ALD on WC powders by blocking adsorption sites on WC and also providing its own sites for Pt particle nucleation. Despite this, the ALD Pt-WC powders were found to be electrochemically equivalent to the ALD Pt-WC thin films through cyclic voltammogram analysis. The Pt-WC powders were also analyzed for ORR using a rotating disk electrode apparatus to obtain quantitative activity information. The mass specific and specific activities for the 30 and 50 ALD cycle samples were found to be comparable to a 10 wt% Pt/C catalyst with more than half the Pt loading. However, the oxygen reduction mechanism on the Pt-WC catalysts was found to be less efficient than on the Pt/C catalyst. Higher overpotentials were observed, and the reduction was found to take the 2-electron peroxide reduction pathway, the less desirable pathway for fuel cell applications. To explain some of the observations in electrochemical activity found with the ALD Pt-WC samples, WC disks with one monolayer of Pt were produced to make idealized surfaces. This system was found to have a lower-than-expected ORR activity, which was attributed to the lack of stability of the WC substrate in oxygen-saturated acid media. Regardless, the Pt-WC core shell system could be potentially useful for other reaction systems, such as hydrogen evolution reaction. Additionally, shape-controlled Pt particles were produced using pulse electrodeposition. By adjusting the applied potential, Pt particles that are spherical, cubic, or dendritic can be made. These were also shown to be useful for the methanol oxidation, a structure sensitive reaction. The dendritic particles were confirmed to be more active than cubic particles, which is in agreement with the literature.

Available in PDF, EPUB and Kindle. Book excerpt: The goal of this project was to develop novel hydrogen-oxidation electrocatalyst materials that contain reduced platinum content compared to traditional catalysts by developing flexible synthesis techniques to fabricate supported catalyst structures, and by verifying electrochemical performance in half cells and ultimately laboratory fuel cells. Synthesis methods were developed for making small, well-defined platinum clusters using zeolite hosts, ion exchange, and controlled calcination/reduction processes. Several factors influence cluster size, and clusters below 1 nm with narrow size distribution have been prepared. To enable electrochemical application, the zeolite pores were filled with electrically-conductive carbon via infiltration with carbon precursors, polymerization/cross-linking, and pyrolysis under inert conditions. The zeolite host was then removed by acid washing, to leave a Pt/C electrocatalyst possessing quasi-zeolitic porosity and Pt clusters of well-controlled size. Plotting electrochemical activity versus pyrolysis temperature typically produces a Gaussian curve, with a peak at ca. 800 C. The poorer relative performances at low and high temperature are due to low electrical conductivity of the carbon matrix, and loss of zeolitic structure combined with Pt sintering, respectively. Cluster sizes measured via adsorption-based methods were consistently larger than those observed by TEM and EXAFS, suggesting, that a fraction of the clusters were inaccessible to the fluid phase. Detailed EXAFS analysis has been performed on selected catalysts and catalyst precursors to monitor trends in cluster size evolution, as well as oxidation states of Pt. Experiments were conducted to probe the electroactive surface area of the Pt clusters. These Pt/C materials had as much as 110 m{sup 2}/g{sub pt} electroactive surface area, an almost 30% improvement over what is commercially (mfg. by ETEK) available (86 m{sup 2}/g{sub pt}). These Pt/C materials also perform qualitatively as well as the ETEK material for the ORR, a non-trivial achievement. A fuel cell test showed that Pt/C outperformed the ETEK material by an average of 50% for a 300 hour test. Increasing surface area decreases the amount of Pt needed in a fuel cell, which translates into cost savings. Furthermore, the increased performance realized in the fuel cell test might ultimately mean less Pt is needed in a fuel cell; this again translates into cost savings. Finally, enhanced long-term stability is a key driver within the fuel cell community as improvements in this area must be realized before fuel cells find their way into the marketplace; these Pt/C materials hold great promise of enhanced stability over time. An external laser desorption ion source was successfully installed on the existing Fourier transform ion-cyclotron resonance (FT-ICR) mass spectrometer. However, operation of this laser ablation source has only generated metal atom ions, no clusters have been found to date. It is believed that this is due to the design of the pulsed-nozzle/laser vaporization chamber. The final experimental configuration and design of the two source housings are described.

Download or read book Final Report Novel Approach to Non Precious Metal Catalysts written by and published by . This book was released on 2007 with total page 307 pages. Available in PDF, EPUB and Kindle. Book excerpt: This project was directed at reducing the dependence of PEM fuel cells catalysts on precious metals. The primary motivation was to reduce the cost of the fuel cell stack as well as the overall system cost without loss of performance or durability. Platinum is currently the catalyst of choice for both the anode & the cathode. However, the oxygen reduction reaction (ORR) which takes place on the cathode is an inherently slower reaction compared to the hydrogen oxidation reaction (HOR) which takes place on the anode. Therefore, more platinum is needed on the cathode than on the anode to achieve suitable fuel cell performance. As a result, developing a replacement for platinum on the cathode side will have a larger impact on overall stack cost. Thus, the specific objectives of the project, as stated in the solicitation, were to produce non-precious metal (NPM) cathode catalysts which reduce dependence on precious metals (especially Pt), perform as well as conventional precious metal catalysts currently in use in MEAs, cost 50% less compared to a target of 0.2 g Pt/peak kW, & demonstrate durability of greater than 2000 hours with less than 10% power degradation. During the term of the project, DOE refined its targets for NPM catalyst activity to encompass volumetric current density. The DOE Multi-Year RD & D Plan (2005) volumetric current density targets for 2010 & 2015 are greater than 130 A/cm3 & 300 A/cm3 at 800 mV (IR-free) respectively. The initial approach to achieve these targets was to use vacuum deposition techniques to deposit transition metal, carbon and nitrogen moieties onto 3M's nanostructured thin film (NSTF) catalyst support. While this approach yielded compounds with similar physicochemical characteristics as catalysts reported by others as active for ORR, the activity of these vacuum deposited catalysts was not satisfactory. In order to enhance catalytic activity additional process steps were introduced, the most successful of which was a thermal treatment. To withstand the high temperatures (~900 ðC), alternative supports to NSTF were introduced. A variety of carbon fabrics were tested for this purpose. Vacuum deposited materials were used as precursors & physicochemically transformed via thermal treatment to produce substantially better catalytic activity. This activity was further amplified by increasing the surface area of the carbon fabrics which lead to significant gains in fuel cell performance. The second synthetic approach is based on 3M nanotechnology & involves depositing precursor catalytic materials on high surface area supports, initially carbon. These materials were subsequently thermally treated in a nitrogen-containing gas atmosphere. While this approach is similar to others reported in the literature, we exploited 3M's nanotechnology platform & our expertise in the areas of synthesis & application of the precursor on the substrate. ORR activity proved higher for the materials produced via this approach. In fact, to our knowledge, the performance achieved on this effort exceeded the best previously reported for any NPM catalyst. With 4-nitroaniline as a precursor, the volumetric current density of our material achieved 19 A/cm3 at 800 mV, exceeding the value reported by DOE as the 2005 status (8 A/cm3) by a factor of more than two. We emphasize a unique feature of this project is that all measurements were done in real PEM fuel cells using 50-cm2 MEAs, therefore rendering credibility to the data for practical projection to a fuel cell stack application. In addition, with the price of the precursor nitroaniline only $1.5 kg on the commodity market enabling the DOE requirement of reducing the cost of the catalyst by a factor of two. A drawback of high-performing catalysts on carbon supports is their poor durability. Therefore, in the last stage of this project the focus of shifted toward improving the stability of the NPM catalyst. For that purpose alternative supports to carbon were introduced, The best catalyst synthesis methods remained practically the same for the new supports. Consequently, catalysts were made that were stable up to 1.4 V & one such material ran for over 1000 hours in a 50-cm2 fuel cell with no significant performance loss. In conclusion, by using precursor materials that are commodity items this project achieved the best performing & the most durable NPM catalyst reported thus far in PEM fuel cells. The knowledge base in the area of NPMC has been substantially increased & a solid platform for reaching the 2010 and 2015 targets of the DOE Multi-Year RD & D Plan has been established.
