对近年来改善Pt催化剂本征氧还原活性的研究进行了系统的总结,发现Pt基合金催化剂和Me@Pt核壳结构催化剂氧还原能力的增强均与Pt化学键的改变导致中间产物吸脱附能力的变化有关,但Pt基合金催化剂和在动态电位以及强酸条件下具有较低的物理结构稳定性和化学稳定性;同时,由于Pt催化剂氧还原能力具有高度的晶体结构依赖性,提高催化剂的高活性晶面是改善催化剂氧还原能力的有效措施。
Abstract:Recent progress of Pt based catalyst towards oxygen reduction reaction is summarized in the current paper.It is found that the activity enhancement of Pt based alloys and core shell catalyst depend on the optimized adsorption of reactive intermediates caused by the changes of Pt chemical bond.The physical structure stability and the chemical stability of these catalysts should be further improved to meet the application requirements.Because of the high crystal structure dependence,Pt catalyst with highly ordered crystal structure is a promising route to improve the oxygen reduction activity.
