Photocatalysis is a prominent alternative wastewater treatment technique that has the potential to completely degrade pesticides as well other persistent organic pollutants, leading detoxification of and thus paving way for its efficient reuse. In addition more conventional photocatalysts (e.g., TiO2, ZnO, etc.) utilize only UV light activation, interest scientific community recently focused on development application visible light-activated like g-C3N4. However, some disadvantages g-C3N4, such high recombination rate photogenerated charges, limit utility. this light, present study focuses synthesis WO3 fibers/g-C3N4 Z-scheme heterojunctions improve efficiency g-C3N4 towards photocatalytic removal widely used insecticide clothianidin. The effect two different precursors (urea thiourea) fiber content properties synthesized composite materials was also investigated. All aforementioned were characterized by number techniques (XRD, SEM-EDS, ATR-FTIR, Raman spectroscopy, DRS, etc.). According results, mixing 6.5% W/W fibers with either urea or thiourea derived significantly increased activity resulting composites compared precursor materials. order further elucidate most photocatalyst in degradation clothianidin, generated transformation products tentatively identified through UHPLC tandem high-resolution mass spectroscopy. Finally, process assessed combining results an in-vitro methodology predictions in-silico tools.

Hydrogen sulfide (H2S) is an important respiratory biomarker of many diseases, and thus, developing H2S gas sensors with low detection limits at operating temperatures essential for the early diagnosis diseases in low-resource environments. Although lead halide perovskites have unique electronic optical properties, high toxicity has prompted development alternative materials. In this study, Cs2AgBiCl6 was synthesized using a simple method. The sensor based on showed excellent sensing room temperature over wide humidity range, response (90.6 vs 10 ppm H2S) fast speed (99.6 s 400 ppb H2S). limit (5 H2S), selectivity excellent. Small changes concentration (<100 ppb) were detected as fully reversible resistance signal. Additionally, sum frequency vibration spectroscopy DFT calculations that sensitivity attributed to physical adsorption Cl vacancies surface Cs2AgBiCl6, well efficient charge transfer. This work provides avenue high-performance nontoxic, band gap, double perovskite semiconductors temperature.
