Summary: Rationally designing heterojunction photocatalysts with well-defined nanostructures and intimate interfacial contact significantly improves the photocatalytic hydrogen evolution reaction (HER) activity. The 1D CdS/2D MoSe2 heterostructure exhibited an enhanced hydrogen-evolving rate of 25.8 mmol g(-1) h(-1) with an apparent quantum efficiency of 30% at 420 nm, attributed to the synergistic effect between the CdS nanorods and MoSe2 nanosheets in accelerating electron-hole separation and interfacial charge transport. This study suggests that morphology control and interfacial engineering can effectively tune the efficiency and long-term stability of heterojunction photocatalysts for hydrogen production, providing insights for robust high-performance visible light photocatalysts.

Summary: Growing nano-CuO on the surface of CdS nanorods by a simple solution-phase reaction greatly enhances the hydrogen evolution ability of CdS. The loading of CuO nanoparticles does not influence the morphology and crystal structure of CdS, but it can delay electron recombination and improve the hydrogen evolution performance of CdS. The photocatalytic performance of CdS significantly increases after loading with 1 wt% Nano-CuO.

Summary: This research demonstrates the excellent photocatalytic hydrogen evolution capability of a composite bimetallic sulfide ZnCo2S4 and CdS. The synergistic effect of zinc ions and cobalt ions enriches the redox-active sites, improving the hydrogen production efficiency of the catalyst. The experimental results show that the hydrogen evolution amount of the composite catalyst is 10 times that of single CdS, and the catalyst exhibits good stability. The apparent quantum efficiency of the composite catalyst with the best hydrogen evolution activity reaches 17.96%. This work provides a feasible method for expanding the application of CdS in the field of photocatalytic hydrogen evolution.

Summary: In this study, a Ni/Ni3S2/CdS composite photocatalytic system was developed by a simple solvothermal method. The calcination process resulted in the best hydrogen evolution performance, with CdS acting as the photosensitizer and Ni as the catalytic active species. The formation of Ni3S2 between Ni and CdS played an important role in charge separation. The Ni loading was regulated by adjusting the annealing time and the molar ratio of Ni salt to CdS, leading to an efficient photocatalytic hydrogen evolution.

Summary: Inactivation of bioaerosols is crucial in preventing the spread of microbial pathogens in the air. Traditional photocatalytic inactivation processes are time-consuming and generate insufficient reactive oxygen species (ROSs) to irreversibly inactivate bacteria. A new photocatalytic ozonation (PCO) system was developed in this study, utilizing NiFeOOH nanosheets on nickel foam and trace concentration of ozone. The PCO system demonstrated a remarkable inactivation efficiency of 99.99% within a short retention time of 8.07 s, with no bacteria surviving after 24 h cultivation. This novel PCO system offers a more efficient method for bioaerosol inactivation and reduces the risk of exposure.

Summary: Most commercial air purifiers use dense fibrous filters to control bioaerosols, but these filters only filter particulate matter based on size and lack bactericidal activity. In this study, a bifunctional nickel foam filter was developed with two layers of coupling nickel foams deposited by CT and PDA, which showed remarkable non-size dependent bacteria removal efficiency (93.5%) and inactivation efficiency (around 70%) within 20 minutes at high airflow. The inactivation efficiency could be further increased to 99.99% with prolonged irradiation time and enhanced light intensity. This pioneering study may provide new insights into the development of bifunctional filters for non-size dependent capture and photocatalytic inactivation of bacteria in bioaerosols.
