摘要: Abstract The palladium-ionic liquids-nitrogen-doped graphene nanocomposites are facile fabricated as enhanced electro-catalyst for ethanol oxidation. First, the ionic liquids functionalized nitrogen-doping nanosheets (PDIL-NGS) with few layers is synthesized through a and effective one-pot hydrothermal method oxide raw material, urea reducing-doping agents (ILs) derived from 3,4,9,10-perylene tetracarboxylic acid functional molecules. results of systematic characterization reveal that PDIL molecules not only can functionalize NGS by π-π stacking no affecting nitrogen doping but also prevent agglomeration NGS. More importantly, processing performance property electron transfer remarkably duo to introducing large number ILs groups. Then, electrocatalytic Pd nanoparticles successfully anchored on PDIL-NGS surfactant-free synthetic technique. As an anode catalyst, novel catalyst exhibits better kinetics, more superior performance, higher tolerance electrochemical stability than other catalysts toward electrooxidation, owing role Therefore, new believed have potential use direct alcohol fuel cells in future promising useful materials applied fields.
