▎ 摘　　要

NOVELTY - Method for preparing tungstenoxide-reduced graphene oxide nanoparticles comprises (a) taking equal volume tartaric acid solution and sodium tungstate solution, mixing the solution, adjusting the pH of the solution to 0.8-1.1, stirring for 1 hour, transferring the mixed solution into the reaction kettle for hydrothermal reaction, (b) adding isopropanol, Nafion (RTM: Sulfonated tetrafluoroethylene based fluoropolymer-copolymer ) solution and reduced graphene oxide, ultrasonically to completely disperse uniformly, (c) coating on two sides of the pretreated carbon cloth, and naturally drying to obtain the final product, (d) using water to centrifugally clean for 3-5 times, (e) centrifuging the ethanol for 1 time, and (f) vacuum drying. USE - The method is useful for preparing tungstenoxide-reduced graphene oxide nano-particle for a microbial fuel cell, which is useful as a device for directly converting chemical energy in organic matter into electric energy by using micro organism. ADVANTAGE - The method overcomes the problem that the current microbial fuel cell anode has high anode potential, low power, and a short period.
