This book was released on 2016 with total page 237 pages. Available in PDF, EPUB and Kindle. Book excerpt: To provide alternative electrocatalysts for energy conversion and storage applications, the catalysts development including materials design, synthesis and growth mechanism, electrochemical diagnose, and reaction mechanism have been investigated and analyzed. Based on the research results in this dissertation, 8 first-authored journal papers have been published/submitted or in preparation. The research results here demonstrate a generic solid-state chemistry method for mass production of platinum group metal/alloy nanoparticles with size/shape/composition control, which could be used in multiple applications such as ammonia electro oxidation, oxygen reduction reaction, hydrazine decomposition, and carbon monoxide preferential oxidations. A highly ordered mesoporous carbon-based nanostructures as non-noble metal catalysts were also studied for oxygen reduction reaction and water splitting. To better understand the surface and interface behavior of platinum alloy catalyst under realistic reaction conditions, in-situ transmission electron microscopy was applied to dynamically investigate the real-time structure evolutions. The findings here also provide insights for establishing realistic structures-properties-applications relationships for materials science, catalysis and electrochemistry.
