Plasma engraved Bi0.1(Ba0.5Sr0.5)0.9Co0.8Fe0.2O3?δ perovskite for highly active and durable oxygen evolution

摘要

catalyst, which outperforms most of the reported perovskite catalysts. The present work provides new insights into exploring efficient catalysts for OER, and it suggests that, in addition to the extensively applied for surface treatment of various catalysts such as carbons and metal oxides, the plasma engraved perovskite materials also exhibits great potential as precious metal-free catalysts.
