Summary: This paper introduces the development and proof-of-concept testing of a trace analysis technique called F-SPE, which combines a fluorescent sensor with solid phase extraction (SPE) to simplify the procedure while maintaining low limits of detection (LOD). The technique involves concentrating an analyte onto a fluorophore-modified membrane and measuring its amount by quantifying the quenching of the fluorophore. The method was demonstrated by impregnating a SPE membrane with a perylene diimide (PDI) fluorophore for the low-level detection of organic amines and amine-containing drugs.

Summary: In recent years, water scarcity has become a significant problem due to population growth, industrial progress, and climate change. Water pollution caused by hazardous pollutants like toxic metals and phenolic compounds demands urgent attention. Coal fly ash and coal bottom ash wastes have been explored as low-cost raw materials for producing suitable materials for cleaner wastewater treatment. These materials have shown promise in removing toxic metals and phenolic compounds through adsorption, membrane filtration, and photocatalysis. Future research should focus on recycling coal ashes and advancing processes for more efficient wastewater remediation.

Summary: Air pollution caused by particulate matter and ozone in Chinese megacities is a major health concern, partially due to the emissions of nitrogen oxides. Therefore, advanced methods, such as photocalysis using polymeric carbon nitride, are needed for nitrogen oxide removal. However, this process is limited by low visible-light absorption, specific surface area, carrier recombination, and conversion pathways. In this review, catalysts made of polymeric carbon nitride for the removal of nitrogen oxides are discussed, focusing on improving light absorption, increasing surface area, inhibiting carrier recombination, regulating the reaction process, outdoor applications, and reducing nitrogen oxides to dinitrogen.

Summary: A photoreduction method was used to immobilize Ni single atoms on CdS nanoparticles, forming an electric metal-semiconductor interaction (EMSI) that greatly promoted H2O-to-H-2 conversion under simulated sunlight. The nanocatalyst with 1.25‰ Ni loading achieved the highest conversion rate and photostability, along with improved light absorption capacity and photexciton utilization efficiency. Under alkaline conditions, OH- ions reacted with photogenerated holes to inhibit oxidation and enhance conversion performance. This study provides insights for improving photocatalyst performance through non-noble metallic single-atom cocatalysis.

Summary: Photothermocatalysis is a process that combines thermal and light energies, and ceria is a promising candidate as a photothermocatalyst for VOCs combustion. However, the impact of its exposed facets on photothermocatalytic activity is not well understood due to a lack of suitable facet control strategies. In this study, we used a MoO42- inducing method to modulate the exposed facets of CeO2 nanorods and investigated their effect on toluene combustion. Our results showed that CeO2 nanorods with the (100) and (111) facets exhibit higher thermocatalytic activity for toluene combustion compared to nanorods with only the (111) facet, and the (100) facet is more easily photo-activated, leading to a significant enhancement in activity when both thermal and light energies are involved. In situ FTIR analysis revealed the possible reaction mechanism of photothermocatalytic toluene combustion over ceria. This study provides new insights into the correlation between ceria exposed facets and photothermocatalytic activity.
