“…In addition, the XRD diffraction peak of ZnCd-PBA has a slight shift compared with the diffraction peak of Cd-PBA (PDF#89-3740). It indicated that ZnCd-PBA was successfully prepared by the introduction of Zn 2+ . In Figure b, no diffraction peak of ZnCd-PBA appeared when ZnCd-PBA combined with CdS.…”

The design of an S-scheme heterojunction can promote the transfer of photogenerated electrons, which is an effective method to improve the activity of photocatalytic hydrogen production. In this work, CdS/ZnCd-PBA composite catalysts were prepared by a simple physical method, and a CdS/ZnCd-PBA S-scheme heterojunction was designed. The close contact between the interface of the two catalysts is conducive to the rapid transfer of photogenerated carriers, providing a new path for electron transfer. The hydrogen production of a CdS/ZnCd-PBA catalyst with a ZnCd-PBA content of about 15% was 962 μmol under simulated light for 5 h, which was 13 and 916 times higher than those of CdS and ZnCd-PBA, respectively. At the same time, CdS/ZnCd-PBA-15 composites also showed good long-term stability. It shows that the construction of the S-scheme heterojunction promotes the separation of electron–hole pairs, which can effectively improve hydrogen production activity.

“…It indicated that ZnCd-PBA was successfully prepared by the introduction of Zn 2+ . 28 In Figure 3b, no diffraction peak of ZnCd-PBA appeared when ZnCd-PBA combined with CdS. This may be because the content of ZnCd-PBA is low, and the strong diffraction peak of CdS shields the diffraction peak of ZnCd-PBA.…”

“…However, the catalytic performance of MOFs is easily affected by the solvent and temperature, which limit their development to a certain extent . Using MOFs as precursors to prepare metal sulfide semiconductor materials with hierarchical structure can improve their stability, as well as inherit the complex morphology and specific surface area of MOFs. − …”

Developing photocatalysts with excellent H 2 evolution performance has been an urgent concern for practical application. Herein, Ni-doped Mn 0.5 Cd 0.5 S was prepared using one-step alkaline hydrothermal strategy. Investigation shows that doping Ni element can enhance the performance of Mn 0.5 Cd 0.5 S. 3% Nidoped Mn 0.5 Cd 0.5 S can obtain the highest rate at 108.3 mmol g À1 h À1(λ > 420 nm), and nearly 14.4 times more than undoped counterpart (7.5 mmol g À1 h À1 ). The defect level formed in Mn 0.5 Cd 0.5 S after doping Ni can make the band gap decrease to 2.35 eV and act as electrons capture center, which promoting charge separation and transfer. Meanwhile, the range of light absorption become wider. This research provides a promising way to enhance the catalytic activity for solid solution through simple element doping.
