Two-dimensional(2d)materials have come to light due to their unique thickness that owns abundant exposed edges with enhanced electrocatalytic properties.2d molybdenum disulfide(MoS_(2))nanosheet has aroused considerable attention due to its tunable surface chemistry and high electrochemical sur-face ***,several shortcomings associated with MoS_(2),such as its naturally existing semi-conducting 2H phase,which has limited active sites due to the inert basal plane,restrict its application in water *** into account the benefits of the 1T/2H phase of MoS_(2),as well as the importance of engineering 2d/2d heterojunction interface for boosted electrocatalysis,metallic Ti_(3)C_(2)Tx was integrated with 1T/2H MoS_(2) to develop 2d/2d 1T/2H MoS_(2)/Ti_(3)C_(2)Tx heterostructured ***,with only 25%of the intercalating agent,1T/2H MoS_(2) with the highest 1T phase content of~82%was successfully *** was further incorporated with 1 wt%of Ti_(3)C_(2)Tx through a com-bination of ultrasonication and mechanical stirring *** 1T/2H MoS_(2)(25d)/Ti_(3)C_(2)Tx-1(MTC-1)manifested outstanding electrocatalytic performance with an overpotential and Tafel slope of 280 mV(83.80 mV dec^(-1))and 300 mV(117.2 mV dec^(-1)),for catalyzing acidic and alkaline medium HER,***,the as-prepared catalysts also illustrated long-term stability for more than 40 *** coupling method for the 2d nanosheets is crucial to suppress the oxidation of Ti_(3)C_(2)Tx and the restack-ing issue of 2d *** superior HER activity is ascribed to the synergistic effect between the heterostructure,enhancing the electronic structure and charge separation *** intrinsic prop-erty of the catalyst further confirms by turnover frequency(TOF)*** such,this research paves the way for designing high-efficiency 2d electrocatalysts and sheds light on the further advancement of tunable 2d electrocatalysts for robust wa
