A roadmap to efficient nickel electrocatalysts for hydrogen oxidation. This schematic summarizes the design landscape of Ni-based electrocatalysts for alkaline hydrogen oxidation, covering alloys, compounds, doped systems, supported catalysts, heterostructures, and core–shell structures. It also highlights key evaluation indicators—activity, stability, performance—and mechanistic factors including hydrogen binding energy (HBE), hydroxide binding energy (OHBE), and interfacial reaction pathways.
