CuCoS 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 CuCoS/Ni foam (NF) catalysts with various morphologies have been successfully synthesized by controlling the ratio of urea and ammonium fluoride (NHF) based on the hydrothermal method. Urea and NHF ratio exhibit a great influence on the microstructure and the HER catalytic performance of CuCoS/NF catalysts is discussed in detail.

作为一种具有尖晶石结构的过渡金属硫化物，硫化铜钴因其出色的耐久性、低过电位和低塔菲尔斜率而成为一种高效的析氢反应（HER）催化剂。在本工作中，基于水热法，通过控制尿素与氟化铵（NHF）的比例，成功合成了具有各种形貌的硫化铜钴/泡沫镍（NF）催化剂。详细讨论了尿素与NHF的比例对微观结构的重大影响以及硫化铜钴/NF催化剂的HER催化性能。
