Two dimensional porous Ni_(12)P_5 sheet modified Mn_(0.5)Cd_(0.5)S for efficient photo-catalytic hydrogen production

摘要

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.
