Assessing Pt and Ni dissolution mechanism and kinetics of shape-controlled oxygen reduction nanocatalysts

•Pt and Ni dissolution mechanisms are morphology-independent.•Pt and Ni dissolution rates are morphology-dependent.•Increased Pt and Ni dissolution rate above 1 V versus RHE.•In situ ICP-MS evidence of Pt-skeleton nanostructure formation.•Long AST needed for steady state dissolution and catalyst...
