Summary: A heterostructure material g-C3N4/SrZrO3 was prepared by grinding and heating a mixture of SrZrO3 and g-C3N4. The synthesized photocatalysts were characterized by various techniques, including SEM, XRD, XPS, EDS, HRTEM, and infrared spectra. The g-C3N4/SrZrO3 material exhibited visible light absorption ability and significantly higher photocatalytic activity than pristine g-C3N4 or SrZrO3. The enhanced photocatalytic performance was attributed to the efficient separation of photogenerated electrons and holes facilitated by the cooperation of g-C3N4 and SrZrO3, as demonstrated by photocurrent measurements.

Summary: A g-C3N4/WO3-carbon microsphere composite-based photocatalyst was successfully prepared by a one-pot thermal synthesis method for sunlight driven water decomposition to produce hydrogen. The composite photocatalyst exhibited improved photocatalytic properties and stability compared to pure g-C3N4. Under visible light and sunlight irradiation, the hydrogen production efficiency of the photocatalytic water decomposition was significantly enhanced. The addition of carbon microspheres increased the specific surface area of the composite photocatalyst and facilitated the transfer of photogenerated electrons in g-C3N4 nanosheets.

Summary: In this study, a g-C3N4/PDI-g-C3N4 homojunction was fabricated for piezo-photocatalytic atrazine removal, demonstrating superior performance compared to individual photocatalysis or piezocatalysis. The introduction of PDI facilitated electron migration and enhanced piezoelectricity, with the homojunction promoting photoelectron transfer. The porous structure of the g-C3N4/PDI-g-C3N4 was found to be essential for the enhanced piezoelectricity, leading to a high atrazine degradation rate and H2O2 production during the piezo-photocatalytic process.

Summary: The highly-efficient TiO2{001}/g-C3N4 (TCN) heterostructures were successfully fabricated using an in situ ethanol-thermal method, with the g-C3N4 structure evolving from bulk to nanosheets, nanocrystals, and quantum dots as the synthesis temperature increased. The optimal TCN-2 heterostructure showed excellent photocatalytic activity for H-2 evolution under visible-light irradiation, attributed to the enhanced crystallinity of TiO2{001} nanosheets and the large surface area g-C3N4 nanocrystals.

Summary: This study investigated the colonization of microbes on microplastics and its impact on the bioaccessibility of pollutants. It found that the biofilms formed on microplastics enhanced the desorption and bioaccessibility of microplastic-sorbed sulfamethazine in organisms. The study also revealed that the interaction between gastrointestinal components and biofilm components played a critical role in this process. Photoaging treatment decreased the enhancing effects of biofilms.

Summary: Petroleum hydrocarbon pollutants can migrate and spread in soil, causing pollution during the extraction, processing, and transportation of crude oil. This study simulated the vertical migration of crude oil in uncontaminated soil around typical oilfields. The results showed that the crude oil contaminants were mainly concentrated in soils above 15 cm and the migration amount was positively correlated with the initial oil concentration. Rating: 8/10.
