Abstract

CuCo2S4 as a spinel-structured transition metal sulfide is a highly effective HER catalyst due to its excellent endurance, low overpotential, and low Tafel slope. In this work, the CuCo2S4/Ni foam (NF) catalysts with various morphologies have been successfully synthesized by controlling the ratio of urea and ammonium fluoride (NH4F) based on the hydrothermal method. Urea and NH4F ratio exhibit a great influence on the microstructure and the HER catalytic performance of CuCo2S4/NF catalysts is discussed in detail.
