▎ 摘　　要

NOVELTY - A cathode material comprises carbon paper, partially-reduced graphene oxide and platinum. The partially-reduced graphene oxide is supported on surface of carbon paper. The platinum is supported on partially-reduced graphene oxide surface. USE - Cathode material is used for electrocatalytic reduction of oxygen and gas-solid phase electrocatalysis for removing volatile organic pollutants (all claimed). ADVANTAGE - The cathode material with high yield is prepared by simple method. DETAILED DESCRIPTION - INDEPENDENT CLAIMS are included for the following: (1) preparation of cathode material, which involves hydrophilic treating carbon paper to form hydrophilic carbon paper, calcining hydrophilic carbon paper to obtain calcined product, placing calcined product in dispersion of graphene oxide, ultrasonically processing calcined product, to obtain calcined product of gravitized graphene, reducing graphene portion of product to obtain calcined product of partially-reduced graphene oxide on surface and depositing platinum on surface of partially-reduced graphene oxide; and (2) usage of cathode material for electrocatalytic reduction of oxygen and gas-solid phase electrocatalysis for removing volatile organic pollutants.
