摘　　要：近年来,石墨烯因其在催化反应过程中具有较大的比表面积、较高的电导率和热导率以及较强的稳定性,而作为电催化剂的载体材料,为燃料电池领域开辟了新的途径。综述了近几年以石墨烯为载体,负载单一类和多类金属以及金属氧化物所合成的石墨烯基复合金属纳米材料在燃料电池领域的研究进展;分析评估了各种复合材料对醇类小分子的电催化氧化的催化活性,并详细阐述了石墨烯作为金属催化剂载体在燃料电池领域的应用。提出今后研发方向为新型高性能,并用廉价金属来替代贵金属,在降低金属使用成本的同时从可控的纳米结构和尺寸等方面来最大化地提升催化剂的电催化性能,将其推广到诸如生态学、传感和纳米医学等应用领域。In recent years,graphene as a carrier material for electrocatalysts,has opened up new avenues for the field of fuel cells due to its large specific surface area,high electrical conductivity and thermal conductivity,and strong stability during the catalytic reaction.The research progress of graphene-based composite metal nanomaterials synthesized with graphene as carrier and supported by single and multi-metals and metal oxides in the field of fuel cells was reviewed.The catalytic activity of various composite materials for the electrocatalytic oxidation of small alcohol molecules was analyzed and evaluated.The application of graphene as a metal catalyst carrier in the field of fuel cells was described in detail.It is proposed that the future direction of further research and development is a new type of high performance,and that precious metals be replaced with cheap metals,and while minimizing the cost of metal use,the electrocatalytic performance of the catalyst is maximally increased from controllable nanostructures and sizes,and it is extended to applications such as ecology,sensing,and nanomedicine.
