Effect of urea and ammonium fluoride ratio on CuCo(2)S(4)/NF as a highly efficient HER catalyst

CuCo(2)S(4) 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 CuCo(2)S(4)/Ni foam (NF) catalysts with various morphologies have been successfully synthesized by controlling the...

Descripción
Sumario:CuCo(2)S(4) 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 CuCo(2)S(4)/Ni foam (NF) catalysts with various morphologies have been successfully synthesized by controlling the ratio of urea and ammonium fluoride (NH(4)F) based on the hydrothermal method. Urea and NH(4)F ratio exhibit a great influence on the microstructure and the HER catalytic performance of CuCo(2)S(4)/NF catalysts is discussed in detail.
