Abstract
In this paper, a facile one-pot method was employed to synthesize CoNi2S4 and CuCo2S4 with various morphologies. The required overpotentials for CoNi2S4 nanorod and CuCo2S4 cluster are only 111Â mV and 135Â mV, respectively, to reach the current density of 10Â mA/cm2. The Tafel slopes for CoNi2S4 nanorod (53Â mV/dec) and CuCo2S4 cluster (63Â mV/dec) are lower than that for binary systems of CoS2 and NiS2. The CoNi2S4 nanorod shows better long-term durability than CuCo2S4 cluster during the galvanostatic electrolysis. Overall these ternary sulfides exhibit promising activity and fair stability for hydrogen evolution reaction.
