| Abstract: | In this paper, the effect of mass ratio of Ni and Co (wNi:wCo) in initial solution on the structure and properties of Ni-Co-S-O composite catalysts was studied. A three-dimensional petal-like and hierarchically connected nano-structured Ni-Co-S-O composite catalyst was obtained on a nickel foam (NF) substrate by a hydrothermal method. When w Ni:wCo=1:2, the prepared Ni-Co-S-O/NF(1:2) catalyst has a larger electrochemically active area (ECSA) and the best oxygen evolution reaction (OER) catalytic performance in alkaline water electrolysis. In 1 mol·L-1 KOH alkaline solution, Ni-Co-S-O/NF(1:2) only need 61 and 313 mV to achieve the current density of 10 and 100 mA·cm-2 respectively. At the same time, its Tafel slope was 155 mV·dec-1. After tested at a high current density of 100 mA·cm-2 for 24 h in the alkaline solution, the Ni-Co-S-O/NF(1:2) could still maintain sheet structure and displayed a good durability. |
