Abstract
CdS is always regarded as one of the most focused non-noble metal photocatalysts responding to visible light. However, it is difficult to be widely used in the field of photocatalysis because of the rapid recombination of photo-induced carriers. A rational structural design is urgently needed to separate the electron–hole pairs efficiently. Herein, CdS was loaded on NiS nanorod surface to form a dendritic structure CdS/NiS p-n heterojunction for high reactivity of photocatalytic hydrogen production. A maximum hydrogen production rate of 17.1 mmol g−1 h−1 was achieved from 65% CdS/NiS under visible light irradiation. X-ray photoelectron spectroscopy, Mott–Schottky curve, and several photoelectrochemical tests were applied to study the enhancement mechanism. In conclusion, the photocatalytic activity is enhanced mainly because the p-n heterojunction builds a path for the directional charge transfer induced by the internal electric field, which improves the separation efficiency of photo-induced carriers. This research provides suggestions for the design of efficient hydrogen production photocatalysts.
Graphical abstract
CdS is loaded on NiS nanorod to form a dendritic structure CdS/NiS composite catalyst and showed an excellent hydrogen production rate of 17.1 mmol g−1 h−1 which is attributed to the one-way transmission of the photo-induced electrons through p-n heterojunction. NiS is found to be the reaction site of the photo-oxidation reaction but not of reduction reaction, while CdS is the main source of the photoinduced charge carriers and the place where hydrogen generated.
