Abstract
The hydrogen evolution reaction(HER)and the oxygen evolution reaction(OER)are the two half reac-tions that make up the over water splitting reaction.Increasing oxygen evolution reaction rate wound immensely raise the efficiency of over water splitting reaction because it is the rate limiting reaction in water splitting reaction.The key to improve OER performance is the development and utilization of advanced catalysts.As one of the most potential catalysts for HER,it has gradually attracted the atten-tion of researchers in the aspect of catalytic OER.It is very necessary to review the research progress of Transition metal dichalcogenides(TMDs)in catalytic OER to promote the research process in the field.In this review,we comprehensively and systematically summarized the strategies to improve TMDs electro-catalytic OER.First of all,structural regulation of TMDs-based electrocatalyst was summarized in detail,mainly including size engineering,defect engineering,doping engineering,phase engineering and hetero-junction engineering.Once more,magnetic field regulation as a representative of external field regulation to improve TMDs electrocatalytic OER performance was discussed in depth.Last but not least,the strate-gies to improve TMDs electrocatalytic OER is prospected and some views on the development of this field are also put forward,which are expected to enhance the catalytic efficiency of TMDs for OER.
