Abstract
Large specific surface is beneficial to improve the performance of catalyst in the application of water photolysis. In this work, we designed and successfully prepared the metal compound Ni-Glycerate with a large specific surface area, and combined it with Zn0.5Cd0.5S to form Zn0.5Cd0.5S@Ni-Glycerate core-shell structure nanocomposites. It was revealed that the introduction of nickel-glycerate can promote the separation of photoinduced charges and accelerate the photocatalytic water decomposition reaction. The optimized H2 production rate on Zn0.5Cd0.5S@Nickel-glycerate (3%) can reach 2800 μmol/h/0.1 g, about 6 times that of pure Zn0.5Cd0.5S. This work indicates that the sulfide-metal organic complex can play a synergistic role in the entire photocatalytic reaction.
