This book was released on 2011 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Artificial photosynthesis, where one uses electricity from solar, or wind, to convert water and carbon dioxide into a hydrocarbon fuel could provide a viable route to renewable fuels but so far the results have been stymied because of the lack of a CO2 conversion catalyst that operates at low overpotentials. In this study we report a catalyst system that shows CO2 conversion at low overpotentials. The system uses two different catalysts to achieve the conversion. First an ionic liquid or ionic salt is used to catalyze the formation of a (CO2)0̐Ư intermediate. Then a transition metal is used to catalyze the conversion of the (CO2)0̐Ư intermediate into useful products. CO formation is first observed at -250mV with respect to a standard hydrogen electrode compared to 800mV in the absence of the ionic liquid. Thus, CO2 conversion to CO can occur without the large energy loss associated with a high overpotential raising the possibility of practical artificial photosynthesis. The reduction of CO2 in 1-ethyl-3-methylimidazolium tetrafluoroborate (EMIM BF4) was studied in an H-type electrochemical cell, an in-situ SFG/SERS cell, and a continuous flow CO2 electrolysis cell. Results from these experiments suggest that the EMIM BF4 is able to catalyze the reaction in such a way that opens the door for the practical low potential and temperature conversion of CO2.

Available in PDF, EPUB and Kindle. Book excerpt: Sustainability, defined as the way to meet the needs of the present generation without compromising the ability of future ones to meet their own, is one of the main challenges of modern society. Within this context, chemistry plays a significant role, and solvent nature as well as its environmental impact are pivotal issues frequently addressed. Ionic liquids, i.e. organic salts that have melting temperatures lower than 100 °C, have been frequently hailed as alternatives to conventional organic solvents. Their greenness has been mainly ascribed to their low vapor pressure and flammability. However, in addition to this, their high solubilizing ability and low miscibility with conventional organic solvents frequently allow for reducing the amount used, as well as for their recycling. Ionic liquids, especially the ones featured by aromatic cations, are frequently described as “polymeric supramolecular fluids” constructed through the establishment of feeble but cooperative supramolecular interactions like Coulomb and π-π interactions, as well as hydrogen bonds. In general, ionic liquids are also indicated as “designer solvents” as it is possible to tailor their features to specific applications by simply modifying their cation or anion structure. In this way, small changes in the ion’s structure can give rise to solvents showing very different properties. The above premises widely justify the growing interest in the properties and applications of ionic liquids, seen in recent literature (according to Scopus, more than 27,000 papers published in the last five years have “ionic liquids” as a keyword). Thanks to their properties, they have been variously used as solvent media, solvents for the obtainment of gel phases, components in the building of dye-sensitized solar cells, media for the preparation of thermochromic materials, etc. This Research Topic aims to present how structural features can determine not only the properties of ionic liquids, but also their possible employment. In this latter case, the interest arises from their ability to affect the outcome of a given reaction in terms of rate, yield, and nature of the products obtained for general use in the field of materials chemistry. This article collection is dedicated to Prof. Kenneth R. Seddon for his outstanding contribution to the formation and development of the ionic liquids community.

Available in PDF, EPUB and Kindle. Book excerpt: One of the crucial challenges in the energy sector is the efficient capture and utilisation of CO2 generated from fossil fuels. Carbon capture and storage technologies can provide viable alternatives for energy intensive processes, although implementation of large-scale demonstrators remains challenging. Therefore, innovative technologies are needed that are capable of processing CO2 emission from a wide range of sources, ideally without additional fossil energy demand (e.g. solar driven or overcoming the limits of photosynthesis). This book covers the most recent developments in the field of electrochemical reduction of CO2, from first-principle mechanistic studies to technological perspectives. An introduction to basic concepts in electrochemistry and electrocatalysis is included to provide a background for newcomers to this field. This book provides a comprehensive overview for researchers and industrial chemists working in environmental science, electrochemistry and chemical engineering.

Download or read book Towards the Low Temperature Reduction of Carbon Dioxide Using a Polymer Electrolyte Membrane Electrolysis Cell written by Anuradha Soundiramourty and published by . This book was released on 2015 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The main objective of this research work was to put into evidence the electrocatalytic activity of various molecular compounds with regard to the electrochemical reduction of carbon dioxide, at low temperature, in view of potential application in PEM cells. First, reference values have been measured on copper and nickel metals. Then the performances of some molecular compounds have been measured. The electrochemical activity of these different compounds has been put into evidence by recording the current-potential relationships in various media. The role of a hydrogen source for the reduction processes has been evaluated. The formation of reduction products has been put into evidence and analyzed by gas phase chromatography. Then, a PEM cell has been developed and preliminary tests have been performed. PEM cells with either an oxygen-evolving anode or a hydrogen-consuming anode have been tested. Using nickel molecular complexes, it has been possible to lower the potential of the cathode and to reduce CO2 but the parasite hydrogen evolution reaction was found to remain predominant.
