Heat-Treating Self-Assembled Metalloporphyrin As Electrocatalysts for Oxygen Reduction Reaction

Proton exchange membrane fuel cell (PEMFC) is a clean and efficient energy-conversion technology, which has been widely expected to replace internal combustion engine to drive future vehicles. A crucial component of PEMFC is Pt/C electrocatalysts that are composed of 2-5 nm semi-spherical Pt particles supported on carbon. However, conventional Pt/C electrocatalysts confront the high costs, limited supply, low activity, easy poisoning and poor durability, preventing PEMFC from commercialization. To resolve these issues, new generation of electrocatalysts have to be rationally designed and synthesized. This talk will focus on the creation of non-precious metal electrocatalysts by heat-treating self-assembled metalloporphyrin molecules and the electrochemical performance toward oxygen reduction reaction. This work was partially supported by the National Key Basic Research Program of China (973 Project 2012CB215500), and National Natural Science Foundation of China (NSFC 21003114, 21103163 and 21373211).
