The rational design of complex PtAu double nanoframes for enhanced electrocatalytic activity in the methanol oxidation reaction is reported. The nanoframes are synthesized through a controlled process involving Au growth, selective Pt deposition, and Au etching, resulting in nested octahedral and truncated octahedral nanoframes with tunable intra-nanogap distances. Residual Au atoms on Pt skeletons create plasmonic hot spots that enhance electrocatalytic activity, with the highest activity achieved at the narrowest gap, while triple nanoframes with dense hot regions exhibit a sixfold increase in current density under light irradiation compared to dark conditions.
