Abstract
In the present study, Pd nanoparticles supported on either holey graphene sheets incorporating boron oxides (Pd/BG) or unmodified holey graphene sheets (Pd/G) are prepared through a heat treatment and impregnation method. The synthesized Pd/BG and Pd/G are characterized by Raman, XRD, TEM, XPS and tested as electrocatalysts for formic acid electrooxidation. Pd/G shows sluggish activity towards HCOOH oxidation while Pd/BG shows obviously enhanced catalytic activity and stability. We propose that the smaller Pd particle size and electron transfer caused by incorporation of boron oxides BxOy in the graphene sheets contributes to the improved electrocatalytic performance.
