Designing palladium-based formic acid oxidation reaction (FAOR) catalysts to achieve significant breakthroughs in catalytic activity, pathway selectivity, and toxicity resistance is both urgent challenging. Here, these challenges are addressed by pioneering a novel catalyst design that incorporates topological chemical disorder, developing new class of PdCuLaYMnW high-entropy amorphous alloys with porous network (Net-Pd-HEAA) as highly active, selective, stable FAOR electrocatalyst. This Net-Pd-HEAA demonstrates record-breaking performance, achieving the mass specific activities 5.94 A mg
