Abstract Efficient ethanol oxidation reaction (EOR) catalysts with anti‐poisoning ability and high selectivity are in demand for the widespread application of direct fuel cells (DEFCs). Here, PdSnW ternary alloy nanoparticles synthesized by a facile solvothermal method exhibit an enhanced EOR catalytic performance. CO stripping experiment, X‐ray photoelectron spectroscopy situ Fourier transform infrared employed to study correlation between catalyst structure The oxyphilic Sn W not only provide dangling O−H bond, accelerating subsequent adsorbed intermediate species, but also moderate electron state Pd, enhancing adsorption CH 3 2 OH, thus resulting promotion C−C bond cleavage increased C1 selectivity. As consequence, nanoparticle better stability higher mass activity than those Pd/C, PdSn PdW, respectively. This work offers novel insights strategically design highly efficient electrocatalysts oxidation, further clarifies inherent structure‐activity relationship.
