| Abstract |
There is a growing interest in search for new catalysts to enhance the activity and kinetics of oxygen evolution reaction(OER) as well as oxygen reduction reaction (ORR). Up to now, Ru and Ir metals and oxides haveshown the best OER performance, but their high cost and poordurability severely hinder their commercial applicability.Therefore, it is highly desirable to develop an efficient and low-cost OER catalyst to replace the precious metal-based catalysts. In this study, N-doped hollow mesoporous shell carbon (N-HMSC) is prepared as a uniform model electrocatalyst by a simple template nanocasting using Fe phthalocyanine (FePc) as a single precursor for carbon, N, and Fe. It is found that the presence of Fe in N-HMSC leads to the efficient graphitization of N-HMSC structure, which can be beneficial for electrocatalytic oxygen evolution reaction(OER). Interestingly, it is observed that Fe is a must for the preparation of high efficient catalyst, but may not be necessary for OER. |
