Bacterial wound infections are one of the growing health and safety threats to the public. In this study, WO 3−x /Ag 2 WO 4 photocatalysts were synthesized, and heterogeneous structures were constructed for nonantibiotic bactericidal use. Due to the heterostructure constructed with Ag 2 WO 4 , the photogenerated carrier separation efficiency and reactive oxygen generation capacity of WO 3−x were improved, which in turn improved the inactivation rate of bacteria. Also, this photocatalyst was loaded into PVA hydrogel for photodynamic treatment of bacterial wound infections. This hydrogel dressing was demonstrated to have good biosafety by in vitro cytotoxicity tests and to have a wound healing-promoting effect by in vivo wound healing experiments. This light-driven antimicrobial hydrogel has the potential ability to treat bacterial wound infections. 27

“…19 Nevertheless, the hydrogen production performance of pure Zn 1−x Cd x S photocatalyst is still unsatisfactory, owing to the rapid carrier recombination that affects the hydrogen production adversely. To further improve the photocatalytic activity of Zn 1−x Cd x S, different morphologies of Zn 1−x Cd x S have been extensively studied, such as 2D nanosheets, 20 nanorods, 21 nanoflowers, 22 0-dimensional (0D) nanoparticles 23 etc. Notably, the 0D Zn 1-x Cd x S nanoparticle structure is favourable for charge transfer during photocatalysis reaction due to its compact charge transfer paths and large specific surface area.…”

We present synthesis of 2D g-C3N4 nanosheets prepared by high-temperature calcination resulting in a series of 2D/0D g-C3N4/Zn0.5Cd0.5S heterojunctions. The structure, microscopic morphology, photoelectric performance, photocatalytic performance, and the mechanism for enhanced photocatalytic performance were studied through various characterization methods. Results indicate that 0D Zn0.5Cd0.5S nanoparticles (ca. 3~5 nm) were uniformly dispersed on the surface of the g-C3N4 and formed a heterostructure. The photoelectrochemical test shows that an appropriate amount of g-C3N4 modification (10%-C3N4/Zn0.5Cd0.5S) can effectively improve the separation and transfer efficiency of photogenerated carriers. In addition, with the amount of g-C3N4, the hydrogen production performance of the g-C3N4/Zn0.5Cd0.5S samples first increased and then decreased. When the amount of loaded g-C3N4 is 10%, the photocatalytic activity of the 10%-C3N4/Zn0.5Cd0.5S is highest, with hydrogen production of 3.53 mmol·g-1·h−1, 2.8-fold higher than that of pure Zn0.5Cd0.5S (1.26 mmol·g-1·h−1). The enhanced photocatalytic performance could be attributed to introduced g-C3N4 which can supply more reaction sites, and the formation of the heterojunction interface which could effectively improve the separation and migration of photogenerated charge carriers. Therefore, designing a low cost and efficient photocatalys without precious metals will provide a feasible solution to meet the increasing global energy demand.
