Two dimensional porous Ni12P5 sheet modified Mn0.5Cd0.5S for efficient photo-catalytic hydrogen production

In this paper, solid solution Mn0.5Cd0.5S (MCS) nanocrystals is modified by two-dimensional (2D) porous Ni12P5 sheet to form Ni12P5/MCS composite, which shows photo-catalytic hydrogen production rate as high as 63.22 mmol g(-1) h(-1). Compared with pure Mn0.5Cd0.5S, the hydrogen production performance is nearly 9 times improved. As a nonnoble metal co-catalyst, the 2D structure and unique electronic properties of Ni12P5 not only promoted the absorption of light, but also effectively inhibited the recombination process of photo-generated carriers. The successful preparation of Ni12P5/MCS composite provided an effective way for improving the photo-catalytic performance of semiconductor materials. (C) 2021 Hydrogen Energy Publications LLC.

Automated summary

In this study, a high-efficiency Ni12P5/MCS composite was successfully prepared by modifying the Mn0.5Cd0.5S nanocrystals with a two-dimensional porous Ni12P5 sheet. The photo-catalytic hydrogen production rate of the composite was significantly improved, reaching 63.22 mmol g(-1) h(-1), which is about 9 times higher compared to pure Mn0.5Cd0.5S. The 2D structure and unique electronic properties of Ni12P5, as a nonnoble metal co-catalyst, not only enhanced light absorption but also effectively inhibited the recombination process of photo-generated carriers.
