In this research, we reported an effective approach to prepare low cost and efficient electrocatalyst for the glycol electrooxidation. The synthetic process involves the replacement reactions between CuCl 2 /H 2 PdCl 4 and Ni nanospheres template. Through controlling the precursor ratio, the Pd/Cu/Ni ratio of the final trimetallic products can be tuned. The prepared electrocatalysts present a monodispersed nanospheres structure with a hollow cavity. The prepared Pd 41 Cu 27 Ni 9 shows the best catalytic activity (0.021 A cm −2 at 0.9 V vs. RHE) for glycol electrooxidation, which is much higher than that of the commercial Pd/C (0.0014 A cm −2 at 0.9 V vs. RHE).
