In the pursuit of solar-driven photocatalytic energy generation, environmental remediation, and carbon neutrality, development semiconductor-based heterojunction photocatalysts presents a promising strategy. However, efficiency pristine ZnIn2S4 (ZIS) is hindered by rapid electron-hole recombination relatively small surface area. Meanwhile, pure graphene oxide (GO) not an ideal photocatalyst due to its inappropriate bandgap presence oxygenated functional groups. To overcome these limitations, surfactant-assisted ZIS synthesis was combined with ammonia-treated GO (NGO) form NGO/ZIS composite that enhances light absorption, charge carrier separation transport, overall hydrogen production under visible illumination. Among evaluated materials, 0.1NGO/ZIS exhibited highest evolution rate (18.8 mmol·g-1 h-1), demonstrating enhancements 3-fold 940-fold increased compared (5.8 h-1) NGO (0.02 respectively. This superior performance attributed improved interfacial transfer between ZIS, facilitated incorporation amine amide groups into GO. Furthermore, density theory (DFT) calculations were conducted validate impact ammonia treatment on support experimental findings. The synthesized characterized using X-ray diffraction (XRD), Fourier-transform infrared (FTIR), photoelectron spectroscopy (XPS), scanning electron microscopy (SEM), transmission (TEM), Brunauer-Emmett-Teller (BET), diffuse reflectance sorption (DRS), photoluminescence (PL), electrochemical impedance (EIS), spin resonance (ESR), time-resolved (TRPL) analyses. study simple yet effective approach fabricating composites, contributing advancement high-performance for sustainable applications.

Co-trimoxazole is an antibacterial drug, a mixture of sulfamethoxazole (SMX) and trimethoprim (TMP) in ratio 5:1. Due to the different susceptibility both components decomposition under influence sunlight, aim study was assess change bacteriostatic activity during irradiation these antibiotics sunlight simulator. The assessed using Microbial Assay for Risk Assessment (MARA), monitoring drug concentrations as well formation photodegradation products liquid chromatography (LC). toxicity analysis SMX TMP showed synergistic six bacterial strains. This maintained even sample when 80–90% degraded. may indicate effect photoproducts and/or lack necessity maintain 5:1 between strong antibiotics. Analysis LC with high-resolution mass spectrometry detector revealed presence 11 degradation products, including two preserved sulfonamide structure, which exhibit activity.
