直接甲醇燃料电池阳极催化剂载体的研究进展

Research of anode catalyst soupport for direct methanol fuel cells(DMFC)

阳极催化反应的反应动力学缓慢是限制直接甲醇燃料电池(DMFC)技术发展的主要原因之一,其中催化剂载体对阳极催化反应有重大影响,载体材料的选择对于决定催化剂乃至燃料电池的性能、效率、稳定性和成本都至关重要。基于对30多篇文献的分析,本文分类综述了用于DMFC碳基催化剂载体包括炭黑、介孔碳、碳纳米管(CNTs)、石墨烯和碳纤维纸,非碳基催化剂载体包括金属有机框架(MOF)、新型二维材料MXenes、钛基材料等材料的研究进展。

The slow reaction kinetics of the anode catalytic reaction is one of the main reasons that limit the development of direct methanol fuel cell(DMFC)technology.Among them,the catalyst support has a significant impact on the anode catalytic reaction.The support material determines performance,efficiency,stability and cost of the catalyst and even the fuel cell.Based on the analysis of more than 30 articles,this article classifies and reviews the carbon catalyst supports used in DMFC,including carbon,mesoporous carbon,carbon nanotubes(CNTs),graphene,and carbon fiber paper;non-carbon catalyst supports include metal organic frameworks(MOF),two-dimensional materials MXenes,titanium-based materials.
