This study investigates the synthesis and evaluation of ZnO/g-C3N4 composites as efficient green catalysts for advanced oxidation processes (AOPs) targeting treatment contaminated water. The were synthesized using a ternary deep eutectic solvent physically–chemically characterized in detail, confirming their structural integrity successful synthesis. Photocatalytic, photo-Fenton- electro-Fenton-like experiments conducted Rhodamine B model contaminant to evaluate catalytic performance, reuse stability material. demonstrated excellent photocatalytic activity under LED light (395 nm), achieving pollutant removal around 59% 90 min. combined effect designed catalyst Fenton-like process, photo-Fenton-like significantly improved this close 95% 60 min due synergistic effects irradiation H2O2 activation. Finally, action process exhibited superior efficiency, 90% within 45 kinetic constants four times higher than those anodic alone. In addition, studies confirmed several cycles with high efficiencies, demonstrating viability long-term scalable water applications. These findings highlight potential through DES sustainable cost-effective alternative remediation technologies.

Versatile Eco‐Friendly Activated Carbon–Based Green Catalysts: Energy and Environmental Applications

ChemBioEng Reviews, Journal Year: 2025, Volume and Issue: unknown

Published: March 30, 2025

Abstract Biomass‐derived activated carbon (AC) offers a sustainable solution for energy and environmental applications. Compared to coal‐based AC, biomass‐derived AC reduces impact while maintaining high porosity adsorption capacity. Its synthesis involves carbonization activation, enhancing properties. Efficiency depends on particle size, surface area, pore structure, functional groups. Smaller particles higher areas enhance adsorption, whereas micropores serve as primary sites. Functional groups influence chemical interactions. Regeneration methods extend usability. AC‐based catalysts improve hydrogen production biodiesel synthesis. In wastewater treatment, iron oxide–impregnated enhances dye removal, titania/AC composites boost photocatalytic degradation of organic pollutants. also plays crucial role in dioxide (CO 2 ) capture, with potassium hydroxide (KOH)‐synthesized optimizing micropore formation. faces challenges biomass supply, logistics, regeneration efficiency, selectivity, requiring innovative activation modifications.
