Summary: Microplastics pose a significant environmental threat, compounded by the lack of efficient removal techniques. Photocatalytic semiconducting nanoparticles show promise in degrading micropollutants, including microplastics. This study presents a novel approach by integrating self-propulsion, phoretic assembly, and photocatalytic oxidation into a single Pac-Man TiO2 micromotor, allowing for active collection and degradation of microplastics. The experiments focus on polystyrene microspheres as model microplastics, correlating degradation with catalytic activity and evaluating timescales for the involved processes.

Summary: This study proposes a controlled strategy to optimize the photocatalytic performance of hybrid catalysts by introducing organic components. The enhanced photocatalytic activity of P-FGDY/TiO2 compared to FGDY/TiO2 is attributed to the regulation of FGDY, which increases the efficiency of photogenerated electron and hole separation. This work provides a novel regulating pathway to optimize the photocatalytic activity of carbon-based hybrid photocatalysis material systems.

Summary: Photocatalytic technology using TiO2 and V-TiO2 as catalysts showed improved degradation efficiency for aniline. The V-doped TiO2 exhibited redshifted absorption band edges, reduced band gap value, improved photocatalytic activity, and broadened optical response range. The optimal V concentration for degrading aniline was found to be 1.5 mol%, and moderate V modification inhibited the complexation of e(-)/h+ pairs effectively.

Summary: In this study, a novel TaB2@TiO2 heterostructure was successfully constructed by a facile sol-gel method. The TaB2@TiO2 heterojunction exhibited suitable work function and B-O bonds at the interface, facilitating the migration of photogenerated carriers. The metallic nanocrystalline TaB2 also increased the specific surface area, leading to improved photocatalytic degradation performance compared to pristine TiO2 and commercial TiO2 (P25).

Summary: The geometric parameters have significant impacts on the properties of photoactivity materials. In this study, the geometric effects on photoluminescence and photodegradation of yolk shell structure were investigated by adjusting the cavity and shell thickness. The results showed that the charge interaction between the core and shell is the main factor for thin shell and cavity samples, while light scattering and accommodation space of intermediates provided by the cavity play a major role in samples with large cavity volume and thick shell. The study also discussed the TC degradation mechanism, possible degradation pathway, major reactive oxidation radical, and toxicity of products in detail.

Summary: This study investigated the adsorption behavior of antibiotics on iron-containing minerals and the effects of co-existing cations and anions. The results showed that quinolones had higher adsorption amounts compared to sulfonamides and mycins. The adsorption isotherms of quinolones could be well fitted using the Freundlich models. The presence of certain cations and anions inhibited the adsorption of quinolones. The adsorption behavior of quinolones on iron-containing minerals in natural surface water samples was also influenced by the environmental conditions. This study provides valuable insights into the transportation and fate of antibiotics in aqueous environments.
