Recent breakthroughs indicate that some oxides such as spinels and perovskites could be used as promising electrocatalysts for ORR (one significant reaction in fuel cells) in alkaline environments to replace scarce noble metals such as Pt. By taking advantage of crystal shape-controlled synthesis, this study centralized on two fronts: facet-dependent effectiveness and structure-dependent effectiveness. The research activities include (1) design and synthesis of state-of-the-art oxide electrocatalysts such as Mn-based spinels with particle shape control and (2) investigation of the correlation between the ORR activity/durability and surface feature of the selected facet-tailored oxide(s).
