Morphology-Controlled Synthesis of V(1.11)S(2) for Electrocatalytic Hydrogen Evolution Reaction in Acid Media

High-performance low-cost catalysts are in high demand for the hydrogen evolution reaction (HER). In the present study, we reported that V(1.11)S(2) materials with flower-like, flake-like, and porous morphologies were successfully synthesized by hydrothermal synthesis and subsequent calcination. The...

description High-performance low-cost catalysts are in high demand for the hydrogen evolution reaction (HER). In the present study, we reported that V(1.11)S(2) materials with flower-like, flake-like, and porous morphologies were successfully synthesized by hydrothermal synthesis and subsequent calcination. The effects of morphology on hydrogen evolution performance were studied. Results show that flower-like V(1.11)S(2) exhibits the best electrocatalytic activity for HER, achieving both high activity and preferable stability in 0.5 M H(2)SO(4) solution. The main reason can be ascribed to the abundance of catalytically active sites and low charge transfer resistance.
