Insight into material design for ORR based on porous organic polymer

氧还原是许多能量转换装置中的关键反应。在简要阐述氧还原反应机理的同时,结合笔者自身团队研究成果重点介绍了近年来新兴的多孔材料(金属有机框架MOF、共轭微孔聚合物CMP等)在电催化中的应用。针对目前电催化剂存在的问题,指出未来的研究思路,包括利用先进的技术手段原位表征催化剂的活性位点,由高活性位逆向推算催化剂的最优结构,优化材料的制备条件。由理论指导实践,在深入认识氧还原反应机理的前提下开发高效稳定、经济环保的新型电催化剂。

Oxygen reduction reaction(ORR)is central to many devices of energy storage and conversion.Along with a succinct introduction of the mechanism of ORR,basing on current research findings of authors’group,focuses on reviewing the status of novel porous materials(i.e.,MOF,CMP,etc.)in electrocatalyst.However,some obstacles such as low activity complex structures of functional carbon materials hindering the commercialization of these catalysts.In terms of the issues,the trend of further development for ORR catalysts was put forward.Great efforts were supposed to be made including the use of advanced technique to identify the active site in suit,predicted the optimal structure for ORR from the high-active site,and optimized the preparation of materials.In addition,theory was combined with practice.Only fully understanding the mechanism of ORR,a new class of electrocatalyst with high efficiency,stability,economy and environment friendly will be developed.
