▎ 摘　　要

NOVELTY - Heteropolyacid, reduced graphene oxide or polypyrrole composite material preparation involves dispersing graphene oxide in deionized water to prepare a suspension of graphene oxide, dissolving heteropolyacid in deionized water to prepare solution of heteropolyacid, and adding pyrrole to the oxidant solution to prepare pyrrole prepolymerization solution. The graphene oxide suspension is mixed with the heteropoly acid solution and isopropyl alcohol for performing photocatalytic reaction to prepare heteropoly acid and reduced graphene oxide suspension. The prepolymer solution is mixed with pyrrole with the heteropolyacid and reduced graphene oxide suspension, and then stirred to react to prepare the suspension of the heteropolyacid/reduced graphene oxide/polypyrrole composite material. USE - Method for preparing heteropolyacid, reduced graphene oxide or polypyrrole composite material (claimed). ADVANTAGE - The method prepares polypyrrole composite material in a simple, cost-effective and eco-friendly manner with high specific surface area, high biocatalysis, high conductivity and good biocompatibility, and can improve microbial fuel cells power generation performance and perchlorate removal performance.
