本发明公开了种CdS/MoS/Mo双层核壳结构光电极的制备方法，步骤如下：以钼网作为基底，以可溶性镉盐作为镉源，将金属镉沉积在钼网上，将沉积好的钼网置于硫化氢气氛中进行硫化，即得到CdS/MoS/Mo双层核壳结构光电极。本发明制备的CdS/MoS/Mo双层核壳结构光电极的光电转化效率高，有较大的应用前景。经实验研究发现CdS/MoS2/Mo双层核壳结构光电极光电化学产氢性能，在光电化学测试中光电流超过三毫安，在主要吸光区域光电转化效率接近20％，性能优于传统FTO玻璃上制备的硫化镉电极。 The invention discloses a preparation method of a CdS/MoS2/Mo double-layer core-shell structure photoelectrode. The method comprises the following steps of taking a molybdenum net as a substrate, taking soluble cadmium salt as a cadmium source, depositing metal cadmium on the molybdenum net, putting the deposited molybdenum net in hydrogen sulfide atmosphere, and vulcanizing to obtain the CdS/MoS2/Mo double-layer core-shell structure photoelectrode. The CdS/MoS2/Mo double-layer core-shell structure photoelectrode prepared by the method has high photoelectric conversion efficiency and has broad application prospects. Experiment research shows that the CdS/MoS2/Mo double-layer core-shell structure photoelectrode has photoelectrochemical hydrogen production performance;
