Sulfur hexafluoride (SF6) is usually used as an insulating medium in gas-insulated switchgear to prevent arc formation electrical transmission and generation systems. Decomposition of SF6 can occur due various faults, detection its decomposition products widely utilized for fault monitoring. Notably, sulfuryl fluoride (SO2F2), a significant component SF6, challenging detect at room temperature. This study presents the synthesis heterojunction comprising zinc oxide (ZnO) microrods tin nanoparticles (SnO2 NPs) through hydrothermal method, followed by integration graphitic-carbon nitrate (g-C3N4) enhance sensitivity toward SO2F2 Incorporating g-C3N4, known extended carrier lifetime, excellent charge mobility, metal-free catalysis properties, significantly elevated gas sensing capability. Enhancement with g-C3N4 led notable increase responsivity 5.6 (2.8) 80 (10) ppm concentrations, marking improvement over 200% low concentrations. investigation underscores efficacy g-C3N4@SnO2–ZnO composite like hazardous temperature, offering potent tool diagnosis within switchgear-based high-voltage safety

Abstract Photocatalysts of TiO 2 –CuO coupled with 30% graphene oxide (GO) were hydrothermally fabricated, which varied the to CuO weight ratios 1:4, 1:2, 1:1, 2:1 and 4:1 reduced form –CuO/reduced (rGO) photocatalysts. They characterized using XRD, TEM, SEM, XPS, Raman, DRS technologies. composites –CuO/GO degrade methylene blue when persulfate ions are present. Persulfate concentration ranged from 1, 2, 4 8 mmol/dm −3 in highest activity 4.4 × 10 –2 7.35 min −1 was obtained for (1:4) (1:1), respectively.

Abstract More and more attention has been paid to the photocatalytic degradation of tetracycline hydrochloride (TCH). Constructing heterojunctions designing defect structures are important means improve separation efficiency photogenerated carriers catalytic activity. ZnO/BWO-x composite was synthesized through solvothermal method. Compared with ZnO BWO-x, a wider visible light absorption range, higher charge migration rate, lower electron–hole pair recombination rate. When molar ratio BWO-O3 is 1:1, prepared photocatalyst (ZnO/BWO-5) highest activity, under irradiation for 180 min, rate TCH reaches 85.53% significantly than that before compounding. After further exploration, it found effect ZnO/BWO-5 best conditions pH = 9, dosage 40 mg, concentration 20 mg l −1 . The reasons enhanced activity composites summarized as follows: (1) Oxygen vacancies reduce band gap utilization light; (2) conduction potential can complement Bi 2 WO 6 , staggered energy levels form Z scheme heterojunction, which conducive rapid carriers.
