主　　题：MoS_(2) Heterostructure Hydrogen Electrocatalysis CNT 

摘      要：High-performance multifunctional materials for water splitting driven by low voltage are crucial for hydrogen evolution reaction(HER),but developing such materials is ***,a simple strategy was designed to build a MoS_(2)/Co_(9)S_(8)/MoC@CNT-N(MCM@CNT-N)heterostructure with a large number of *** the HER,the synthesized MCM@CNT-N heterostructure catalyst showed high efficiency and stable electrocatalytic performance,with a low overpotential of 174.2 mV and a small Tafel slope of 84.7 mV dec^(-1) at a current density of 10 mA cm^(-2) in 0.5 M H_(2)SO_(4).In addition to the function of heterojunctions,the excellent activity is also attributed to the introduction of Co and N atoms and the formation of carbon *** work provides a new approach to build efficient and low-cost electrocatalysts for electrochemical reactions.
