Ultrafine Pd3Pb intermetallic nanowires with Mott–Schottky effect achieve a complete oxidation pathway for methanol oxidation catalysis

Pd 3 Pb IM/MNC with high-density active sites that could simultaneously regulate the adsorption of *OH and *CO shows high power density (225.5 mW cm −2 ) and high stability (31.9% attenuation for 10 hours) in a DMFC.
