摘　　要：采用高温退火法分解一定配比的羧乙基锗倍半氧化物(CGeO)和石墨烯(G)的混合物,制备得到氧化锗/石墨烯(GeO_2/G)复合材料。SEM、TEM等表征手段证实氧化锗成功地复合到石墨烯中。LSV等电化学测试表明,其在酸性介质中表现出良好的催化活性、稳定性和抗甲醇毒性。With high temprature annealing graphene（G） and 3is（2-carboxyethyl gemanium（ Ⅳ） sesquioxide（CGeO）, geranium oxide / graphene（GeO_2/G） composite was synthesized. SEM, TEM, et al. results proved that geranium oxide had been successfully dispersed in graphene. Electrochemical performance tests confirmed that geranium oxide / graphene had an outstanding oxygen reduction electrocatalytic acticity, durability, and ability to resist methnol toxicity than Pt/C in acidic medium.
