Abstract

A stack of basic structural carbon units incorporating phosphorus oxides (P_xO_y) at edges and internal defects is obtained and used as a support material for Pd nanoparticles, with the aim of creating an efficient electrocatalyst for HCOOH oxidation. In contrast to the lack of activity displayed by Pd supported on lyophilized and vacuum-annealed graphene oxides, Pd on holey graphene sheets incorporating P_xO_y (Pd/HGP_xO_y) shows efficient activity and stability in HCOOH oxidation. Surface analysis of fresh and reacted catalysts reveals that HCOOH oxidation is favored by Pd/HGP_xO_y due to the decreased Pd electron density caused by electron transfer from Pd to HGP_xO_y.
