基于MOFs材料的直接甲醇燃料电池电催化剂研究进展

Research Progress of Electrocatalysts for Direct Methanol FuelCells Based on MOFs

直接甲醇燃料电池(Direct methanol fuel cells,DMFCs)因其高能量密度、成本低、结构简单、工作温度低和燃料易于储存和运输等优点备受关注。然而由于最常使用的DMFCs阳极催化剂是商业Pt/C,其高成本和低稳定性严重阻碍了其商业发展。良好的催化剂载体对提高催化剂的电催化性能具有重要意义,金属有机框架(Metal-organic frameworks,MOFs)材料作为一种兴起的材料引起了人们广泛的关注,由于其结构功能的多样性、超大的比表面积、高孔隙度以及可修饰性等特点,在直接甲醇燃料电池催化剂领域具有很好的应用前景。本文综述了MOFs材料及其衍生物在DMFCs中的最新应用进展,并对其存在的不足之处和未来发展方向进行了总结。

Direct methanol fuel cells(DMFCs)have attracted much attention due to their high energy density,low cost,simple structure,low operating temperature,and easy fuel storage and transportation.However,since the most commonly used anode catalyst for DMFCs is commercial Pt/C,its high cost and low stability seriously hinder its commercial progress.A good catalyst support is of great significance to improve the electrocatalytic performance of catalysts.Metal-organic frameworks(MOFs)as a rising material have attracted extensive attention due to their structural and functional diversity,ultra-high specific surface area,high porosity,and modifiability.It has great application prospects in the field of direct methanol fuel cell catalysts.In this paper,the latest application progress of MOFs materials and their derivatives in DMFCs is reviewed,and their shortcomings and future development directions are also summarized.
