This study employed an electrodeposition approach to synthesize multiphasic CuSx and FeSx on nickel foam (NF) for application in saline water splitting. This multiphasic electrocatalyst exhibits a cauliflower morphology and develops a porous fused-type morphology upon partial oxidation. The NF/CuSx/...
