摘要
直接硼氢化物燃料电池(DBFC)是一种将存储在硼氢化物中的化学能(氢能)在阳极催化剂作用下直接转化为电能的新型氢燃料电池。由于该类电池具有理论电池电压高、能量密度大、绿色清洁及便于携带等优点而备受研究者的青睐。DBFC的阳极催化剂是决定电池性能的关键因素。以往阳极催化剂多采用贵金属及其合金。贵金属催化剂具有优越的催化活性和稳定性,但贵金属资源有限且成本高。为降低成本、扩大应用范围,近年来研究人员开始寻找非贵金属催化剂。Co基催化剂是一类非贵金属催化剂,因其活性高、比贵金属便宜等优点而受到研究者的重视。从Co基催化剂的种类、制备方法和性能角度出发,对近几十年来Co基催化剂的研究成果进行分析、梳理。同时对Co基催化剂今后的发展进行展望。
Direct borohydride fuel cell(DBFC)is a new type of hydrogen fuel cell that converts the chemical energy(hydrogen energy)stored in borohydride directly into electrical energy under the action of anode catalyst.This kind of battery is favored by researchers because of its advantages of high theoretical battery voltage,high energy density,green cleaning and portability.However,the anode catalyst of DBFC is a key determinant of battery performance.In the past,precious metals and their alloys were used as anode catalysts.Precious metal catalysts have superior catalytic activity and stability,but their resources are limited and the cost is high.In order to reduce costs and expand applications,researchers have begun to look for non-precious metal catalysts in recent years.Co-based catalyst is a kind of non-precious metal catalyst,which has been paid more attention by researchers because of its high activity and cheaper than precious metal.The research progress of Co-based catalysts in recent decades have been reviewed from the perspective of the types,preparation methods and properties of Co-based catalysts.At the same time,the future development of Co-based catalyst was prospected.
