MoSe₂-Ni₃Se₄ Hybrid Nanoelectrocatalysts and Their Enhanced Electrocatalytic Activity for Hydrogen Evolution Reaction.

ABSTRACT: Combining MoSe₂ with other transition metal dichalcogenides to form a hybrid nanostructure is an effective route to enhance the electrocatalytic activities for hydrogen evolution reaction (HER). In this study, MoSe₂-Ni₃Se₄ hybrid nanoelectrocatalysts with a flower-like morphology are synthesized by a seed-induced solution approach. Instead of independently nucleating to form separate nanocrystals, the Ni₃Se₄ component tends to nucleate and grow on the surfaces of ultrathin nanoflakes of MoSe₂ to form a hybrid nanostructure. MoSe₂-Ni₃Se₄ hybrid nanoelectrocatalysts with different Mo:Ni ratios are prepared and their HER catalytic activities are compared. The results show that the HER
