Highly poison-resistant Pt nanocrystals on 3D graphene toward efficient methanol oxidation

Abstract

Highly poison-resistant and uniformly ultrasmall Pt nanocrystals on 3D graphene are synthesized using reductive sugars derived from pectin hydrolysis, and showed a much greater stability and better electrocatalytic activity than the commercial Pt/C toward methanol oxidation. The highly poison-resistant mechanism is mainly attributed to the electrostatic repelling effect between the remanent pectin modified on the Pt surface and the adsorbed poison reactive intermediate species such as carboxy (–COOH)ad during the methanol oxidation reaction. This work provides great promise for an anode catalyst for direct methanol fuel cells through a green synthetic approach.
