摘要
In this paper, inorganic semiconductor CdS nanorods (CdS-NRs) with strong visible-light absorption was used to modify hierarchically structured Ni-based MOF NMOF-Ni assembled from ultrathin nanosheets. It was found that the HER under simulated sunlight irradiation sharply increases 55.6 times (from 81 to 4500 μmolg−1 h−1) after modification of NMOF-Ni with 10 wt.% CdS-NRs. This enhanced performance originating from the CdS-NRs greatly improves the light absorption, and the imitate contact between NMOF-Ni and CdS-NRs stimulates the charge separation and migration. In addition, CdS-NRs/NMOF-Ni hybridized photocatalyst exhibits excellent photo-stability in hydrogen production due to the protection of NMOF-Ni, which can efficiently prevent the photo-corrosion of CdS-NRs. A direct Z-scheme electron transfer mechanism is proposed for the enhanced simulated sunlight photoreactivity of CdS-NRs/NMOF-Ni hydized photocatalyst towards hydrogen production.
