摘要：Tradition metal selenides have triggered extensive attentions in the field of electrochemical energy storage and conversion. Herein we propose a decent synergetic effect produced by delicate hybridization between exfoliated MoSe2 nanosheets and high conductive Ag nanoparticles (NPs) during self-assemble process. The Ag/MoSe2 hybrid architecture (weight ratio, 5:100) can reach 10 mA cm(-2) current density at a potential as low as 0.187 V, which almost is similar to 3-fold lower than that for the bare MoSe2 nanosheets. Additionally, the Ag/MoSe2 hybrid architecture also exhibits an enhanced capacity, excellent rate abilities and superior cycling stability for lithium storage than pristine MoSe2 nanosheets. The comprehensive explorations of the synergistic effects occurring between MoSe2 nanosheets and Ag NPs have insights for the rational constructions of low cost electrocatalysts for hydrogen evolution as well as high performance electrode materials for lithium storage based on transition metal chalcogenides.
