Appropriate oxygen vacancies and Mo-N bond synergistically modulate charge transfer dynamics of MoO/S-CN for superior photocatalytic disinfection: Unveiling synergistic effects and disinfection mechanism.

Highly efficient charge transfer is a critical factor to modulate the photocatalytic activity. However, the conscious modulation of charge transfer efficiency is still a great challenge. Herein, a novel interfacial Mo-N bond and appropriate oxygen vacancies (OVs) modulated S-scheme MoO/S-CN heterojunction was rationally fabricated for efficient photocatalytic disinfection.

Insights into the role of reactive oxygen species in photocatalytic HO generation and OTC removal over a novel BN/ZnInS heterojunction.

Developing photocatalysts with superior performance to generate hydrogen peroxide (HO) and degrade oxytetracycline (OTC) is an effective strategy for the treatment of energy crisis and water purification. Herein, BN nanosheets were anchored onto the ZnInS microspheres for the research. Experimental and density functional theory (DFT) results demonstrate that due to different work functions and unique 2D/2D contact, the electron is spatially separated in BN/ZnInS nanocomposite, which increases the electron transfer efficiency from 43.

2D/2D Heterojunction systems for the removal of organic pollutants: A review.

Photocatalysis is considered to be an effective way to remove organic pollutants, but the key to photocatalysis is finding a high-efficiency and stable photocatalyst. 2D materials-based heterojunction has aroused widespread concerns in photocatalysis because of its merits in more active sites, adjustable band gaps and shorter charge transfer distance. Among various 2D heterojunction systems, 2D/2D heterojunction with a face-to-face contact interface is regarded as a highly promising photocatalyst.
