Optimized by Disorder Engineering on Iron doped Ni3S2 nanosheets for Oxygen Evolution Reaction

Abstract

Nowadays, disorder engineering of catalytic materials has attracted a great deal of attentions because it can increase catalytic active sites and thus enhance their catalytic activity for electrocatalytic reaction. However, it is extremely needed to further uncover the relationship between the disorder engineering and catalytic activity. Specially, exploring deeply the relationship is so important for fabricating excellent highly active catalysts for oxygen evolution reaction (OER) that is one of promising technologies in energy transition. In this work, we prepare Fe-doped Ni3S2 materials and simultaneously control the disorder degree by regulating ion concentration to improve activity for OER. By investigating as-prepared catalysts with various disorder degrees for OER, we also explore the relationship between the disordered structure and OER catalytic performance. In particular, the optimized electrocatalyst with an appropriate disorder degree shows an excellent activity and stability. We hope that this work provides a feasible direction to fabricate and optimize transition metal chalcogenides (TMCs) electrocatalysts as an efficient and stable electrocatalysts for OER.
