Summary: In this study, two-dimensional materials (nanoscale mono/multi-layer MXene) were prepared and a visible-light-driven photocatalyst MXene@In2S3 was synthesized. The monolayer MXene@In2S3 exhibited better photocurrent response and charge transfer resistance than the multilayer MXene@In2S3 under visible light irradiation. The excellent photocatalytic disinfection performance of MXene@In2S3 was attributed to the oxidation substances produced under visible light irradiation, causing irreversible physical damage to microbial cells and resulting in sustained inactivation.

Summary: Designing photocatalysts with high light utilization and efficient photogenerated carrier separation is crucial for pollutant degradation. In this study, a hierarchical core shell material alpha-Fe2O3@ZnIn2S4 with a tandem heterojunction mechanism and MXene Ti3C2 quantum dots (QDs) was synthesized. The alpha-Fe2O3@ZnIn2S4/Ti3C2 QDs exhibited significantly higher photodegradation efficiency compared to pure alpha-Fe2O3. The enhanced photocatalytic activity was attributed to the S-scheme heterojunction and Schottky junction tandem, which facilitated charge separation. This study provides a new approach for the construction of tandem double heterojunctions for pollutant degradation.

Summary: Doping engineering of metallic elements is important in photocatalysis, especially in the transition element range, as it increases carrier concentration and absorption in the light region. Mn doping changes the local structure of BiOCl, increasing the specific surface area and mesoporous distribution. The combination of Mn doping and metal Bi reduces the forbidden bandwidth, strengthening the photocatalytic ability. The dual-technology combination of Mn doping and Bi metal has promising applications in environmental remediation.
