Regenerated CO Anti-poisoning Ability by Anchoring High Oxidized Platinum on Oxygen Functionalized Carbon Spheres in One-step & Two-phase Synthesis for Methanol Electro-oxidation

Abstract

In this work, a one-step and two-phase solvothermal approach has been employed to synthesize Pt@C-O composite spheres formed by platinum (Pt) nanoparticles (NPs) anchored in oxygen functionalized carbon sphere. The introductions of Platinum (II) 2, 4-pentanedionate (Pt(acac)2), benzoic acid, and chloromethane-glycerol two phases are found to be significant for the formation of Pt@C-O composite nanostructures. Furthermore, as-obtained Pt@C-O composites are investigated to have much more oxidized species of carbon (C-O) and platinum (Pt-O), as compared to commercial Pt/C. Results shows Pt@C-O (CHCl3) catalyst based on the obtained Pt@C-O in chloroform-glycerol mixture exhibits optimal electrocatalytic activity and superior carbon monoxide (CO) tolerance, which is mainly because the oxidation states of carbon and platinum make catalyst regenerate during the methanol oxidation and the CO anti-poisoning process.
