AI Insight
Researchers developed a novel S-scheme S-g-C₃N₄/ZnWO₄ nanocomposite using microwave-assisted synthesis with plant extracts as a green chemistry approach. The nanocomposite demonstrated effective photocatalytic degradation of organic dyes and antibiotics under visible light irradiation, while also exhibiting antimicrobial properties against bacterial pathogens. The S-scheme heterojunction structure enhanced charge carrier separation and photocatalytic efficiency compared to individual components.
Why it matters
This work presents an environmentally friendly synthesis method for photocatalysts that can address multiple pollution challenges simultaneously, including industrial dye contamination, antibiotic residues in water, and microbial contamination. The use of visible light rather than UV radiation makes the technology more practical and energy-efficient for real-world water treatment applications.
