石墨烯用作直接甲醇燃料电池阳极催化剂载体

Modified graphene as anode catalyst for direct methanol fuel cell

直接甲醇燃料电池(DMFC)阳极催化剂是决定电池性能、寿命和成本的关键材料之一。近年来人们主要从提高催化剂活性和降低催化剂成本两个方面出发进行了大量的研究,有力地推动了直接甲醇燃料电池的发展。石墨烯作为一种载体材料能够显著提高催化剂的催化活性和稳定性,引起了人们极大的兴趣。介绍了近几年石墨烯在直接甲醇燃料电池阳极催化剂载体的进展,并对其在未来的应用进行了展望。

Anode catalyst is one of the key materials determining the performance, longevity and cost of direct methanol fuel cell（DMFC）. In recent years, extensive researches effectively promoting the development of DMFC are carried out, and these researches are mainly about two aspects：the activity improvement of catalyst and lowering the cost of catalyst. Graphene as a new carbon material can significantly improve the activity and stability of the catalyst. The research progress of modified graphene as anode catalyst of DMFC in recent years was reviewed and the application in the future was prospected.
