Abstract
Alkaline electrolyzed water hydrogen production technology is of great significance to the development of sustainable alternative energy. Although precious metal Pt is the best electrocatalyst for hydrogen evolution reaction (HER), its alkaline HER involves the two-step reaction of water dissociation and hydrogen recombination, which limits its development in alkaline electrolyzed water technology. Therefore, amount of interface chemistry of materials has been investigated to design catalysts with a large number of active sites and stability to improve the performance of alkaline HER. In this chapter, we summarize the interfacial chemical specificity of the Pt and Pt-based catalysts for controlling alkaline HER kinetics to boost the water dissociation step and hydrogen evolution efficiency. This is a guiding significance for the future of building renewable and sustainable energy systems.
