Graphene supported Pd electrocatalysts for formic acid oxidation
Abstract Highly loaded 80 wt.% Pd/graphene nanosheet (GNS) electrocatalysts were
synthesized by colloidal method in order to alleviate the degradation rate of Pd catalysts in
formic acid oxidation. Pd nanoparticles deposited on the GNS were well distributed on the
surface more homogenously and average particle size of these metals is 4.6±0.6 nm as
compared to Pd/VC (5.0±1 nm), which is verified by X-ray diffraction peak and high-
resolution transmission electron microscope images. Electrochemical measurements …

Abstract
Highly loaded 80 wt.% Pd/graphene nanosheet (GNS) electrocatalysts were synthesized by colloidal method in order to alleviate the degradation rate of Pd catalysts in formic acid oxidation. Pd nanoparticles deposited on the GNS were well distributed on the surface more homogenously and average particle size of these metals is 4.6 ± 0.6 nm as compared to Pd/VC (5.0 ± 1 nm), which is verified by X-ray diffraction peak and high-resolution transmission electron microscope images. Electrochemical measurements conducted by cyclic voltammetry and chronoamperometry show that Pd/GNS catalysts exhibited significantly enhanced electrocatalytic activity and stability for formic acid oxidation compared to Pd/VC catalysts.
