Recent development of new carbon materials with special morphology and ordered porous structure as the electrocatalyst support in fuel cell

特殊形貌和有序孔结构碳载体材料因其独特的结构显示出与常规碳材料不同的性质,在众多领域具有广泛的应用前景。以其作为燃料电池电催化剂载体可显著改善贵金属活性组分的分散度,有利于电极内的物料与电荷传输,进而提高催化剂活性和燃料电池性能。本文综述了近年来以碳纳米管、碳纳米纤维、介孔碳和碳凝胶等新型碳材料作为催化剂载体的研究进展,并对未来的发展趋势进行了展望。

Differing from the traditional carbon,new carbon materials with unique appearance and orderly porous structure have distinctive properties and can be applied to various fields in future.Combining with electrocatalyst support in fuel cells,it can not only be used to markedly improve high dispersion of the noble metal electrocatalyst,but also be facilitated to the mass/charge transfer in the electrode so as to better enhance electrocatalytic activity and fuel cell performance.This review was to summarize the recent development of the carbon materials as catalyst support,including carbon nanotubes,carbon nanofibre,ordered mesoporous carbon,carbon gel and look forward to its trends in the future.
