摘要：
Electrochemical production of hydrogen from water holding tremendous promise for clean energy has been directed to the search for non-noble metal based and earth-abundant catalysts. Here we report dramatically enhanced HER catalysis of ternary I-Cu2WS4 nanosheets from chemically exfoliated via lithium intercalation. Structural characterization and electrochemical study confirmed that the enhanced electrocatalytic activity of I-Cu2WS4 nanosheets is associated with the larger surface area to provide an easy path for the hopping of electrons. This study opens a new way for the development of ternary highly active non-noble electrocatalysts for hydrogen production from water splitting. [GRAPHICS]
