    Novel Nanostructure Electrocatalysts for Oxygen Reduction and Hydrogen Evolution Reactions
    (University of Western Cape, 2020) Lou, Lin; Titinchi, Salam; Abbo, Hanna
    widespread use of fossil energy has been most convenient to the world, while they also cause environmental pollution and global warming. Therefore, it is necessary to develop clean and renewable energy sources, among which, hydrogen is considered to be the most ideal choice, which forms the foundation of the hydrogen energy economy, and the research on hydrogen production and fuel cells involved in its production and utilization are naturally a vital research endeavor in the world. Electrocatalysts are one of the key materials for proton exchange member fuel cells (PEMFCs) and water splitting. The use of electrocatalysts can effectively reduce the reaction energy barriers and improve the energy conversion efficiency. This thesis mainly focuses on development novel nanostructure electrocatalysts with low-cost, high activity and good durability used for oxygen reduction reaction (ORR) and hydrogen evolution. (1) Nitrogen-doped PtNiMo ternary alloys were synthesized by impregnation reduction followed by annealing at high temperatures.
