Download or read book From Intrinsic to Extrinsic Design of Lithium Ion Battery Layered Oxide Cathode Material Via Doping Strategies written by Chul-Ho Jung and published by Springer Nature. This book was released on 2022-10-20 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book addresses the comprehensive understanding of Ni-rich layered oxide of lithium-ion batteries cathodes materials, especially focusing on the effect of dopant on the intrinsic and extrinsic effect to its host materials. This book can be divided into three parts, that is, 1. overall understanding of layered oxide system, 2. intrinsic effect of dopant on layered oxides, and 3. extrinsic effect of dopant on layered oxides. To truly understand and discover the fundamental solution (e.g. doping) to improve the Ni-rich layered oxides cathodic performance, understanding the foundation of layered oxide degradation mechanism is the key, thus, the first chapter focuses on discovering the true degradation mechanisms of layered oxides systems. Then, the second and third chapter deals with the effect of dopant on alleviating the fundamental degradation mechanism of Ni-rich layered oxides, which we believe is the first insight ever been provided. The content described in this book will provide research insight to develop high-performance Ni-rich layered oxide cathode materials and serve as a guide for those who study energy storage systems. ​

This book was released on 2014 with total page 51 pages. Available in PDF, EPUB and Kindle. Book excerpt: A series of nano-sized magnesium oxide particles with both high and low surface areas were successfully prepared by a simple water/toluene reverse microemulsion method using triton X-45, 1-Dodecanol as surfactant. By controlling the amount of surfactant, it is possible to control the size of MgO nanoparticles from 20 nm to 50 nm. The size was confirmed by X-ray diffraction (XRD). In order to investigate the reactivity of OCM reaction over the magnesium oxide support, a series of catalysts were also synthesized. High surface area MgO samples prepared by microemulsion were used as support for Li-TbOx, where 1.75 \U+2264\ x \U+2264\ 2. In order to get the largest coverage of the MgO support and the smallest Li-TbOx particles, a nitrate precursor was used during incipient wetness impregnation, followed by calcination at 800 °C for 4 hours. Another MgO-supported Li-TbOx catalyst was prepared using the same method with the low surface area MgO nanoparticles. Low surface area MgO nanoparticles were also used as OCM catalysts after calcination at 800 °C for 4 hours. N2 adsorption (BET) results showed that the surface area of the catalysts supported on MgO nanoparticles prepared using 15 wt% Triton X-45 was as low as 1.0 m3/g, while the surface area of the catalyst prepared using MgO particle, synthesized with 15 wt% Triton X-45 and 1-Dodecanol mixture was 9.3 m3/g. Oxidative coupling of methane (OCM) catalyzed by the prepared catalysts was studied using a continuous-flow quartz reactor at atmospheric pressure, 500-800 °C at a CH4:O2 ratio of 4:1. The methane conversion reached 21.9% at 700 °C with a C2+ selectivity as high as 65.5%. Thus, a maximum C2+ yield of 13.5% was realized. However, there was a rapid deactivation during the OCM over Li-doped catalysts due to the loss of Lithium.

Book excerpt: The book is a multi-author survey (in 15 chapters) of the current state of knowledge and recent developments in our understanding of oxide surfaces. The author list includes most of the acknowledged world experts in this field. The material covered includes fundamental theory and experimental studies of the geometrical, vibrational and electronic structure of such surfaces, but with a special emphasis on the chemical properties and associated reactivity. The main focus is on metal oxides but coverage extends from 'simple' rocksalt materials such as MgO through to complex transition metal oxides with different valencies.

Available in PDF, EPUB and Kindle. Book excerpt: Dry reforming of methane (DRM) is an environment-friendly and sustainable chemical technique, since it converts methane and CO2, two most abundant greenhouse gases, into syngas and other high value chemical products. The most common catalyst for DRM reaction is Ni due to its low cost and high catalytic activity but Ni-based catalysts undergo severe deactivation due to coking. transition metal (TM) doped rare earth oxide catalysts have shown promise in the high catalytic activity and coking resistance ability. This thesis applies the first principles calculation method to design Ni and Zr doped CeO2 catalyst model. Density functional theory (DFT+U) method is used to generate the structure-composition-stability relationships. The distribution of Zr with multiple concentrations have been studied in the CeO2 fluorite lattice. The oxygen vacancy effect has also been examined in the bulk and surface Ni-doped CeO2 bulk and surface structure to determine the most stable configuration. The surface chemistry study of Ni-doped CeO2 surface shows that hydrocarbon over the surface is always oxidized and prefers bonding to the oxygen site rather than the Ni site. This result can thermodynamically explain the reason of catalyst coking resistance.
