The highly improved hydrogen evolution performance of a 0D/0D MoP-modified P-doped Mn 0.5 Cd 0.5 S photocatalyst.

In this paper, we present a MoP/P-Mn 0.5 Cd 0.5 S photocatalytic material (PMOMCS-P x ). A novel catalyst can efficiently split water into hydrogen without precious metals. In the sacrificial agent environment, the HER (hydrogen evolution rate) of PMOMCS-P5 was 4368.25 μmol g -1 h -1 which was 11.4 times greater than the HER of Mn 0.5 Cd 0.5 S (383.19 μmol g -1 h -1 ), and its hydrogen production performance was better than that of Pt/Mn 0.5 Cd 0.5 S (2.0 wt% Pt). Furthermore, the hydrogen evolution performance of PMOMCS-P5 under pure water conditions was also examined, and the HER of PMOMCS-P5 was 209.76 μmol g -1 h -1 , which was 20.4 times that of Mn 0.5 Cd 0.5 S (10.29 μmol g -1 h -1 ). Its characterization proved that the introduction of the co-catalyst MoP and P doping inhibited the recombination of e - and h + , enhanced the reduction capacity, and reduced the hydrogen precipitation reaction overpotential of PMOMCS-P x , thus enhancing the hydrogen production performance of PMOMCS-P x . Therefore, an efficient and economical photocatalyst was prepared.
