The use of photocatalysis in conjunction with biomass presents an innovative and promising way to increase the sustainability chemical processes. In this work, a g-C3N4@AgFe2O4 heterojunction nanocomposite was prepared by facile sonication method subsequently modified sulfonic acid groups form new acidic photocatalyst enhanced photocatalytic activity. structure, surface composition, morphology, optical absorption features were studied using state-of-the-art characterization techniques. Visible-light-driven dehydration biomass-derived carbohydrates 5-hydroxymethylfurfural (HMF), as versatile platform compound, employed assess its catalytic property. Compared traditional homogeneous heterogeneous catalysts, reveled superior or equal activity production HMF from fructose only at low temperature (90 °C, 91% yield). easily recovered remained active recycle runs, approving good stability. Furthermore, developed protocol found be capable converting other feedstocks, such glucose, sucrose, maltose into respectable yields. Interestingly, work represents first example utilizing photocatalyst.

Recent Progress in g-C3N4-Based Photocatalysts for Organic Pollutant Degradation: Strategies to Improve Photocatalytic Activity

Catalysts, Год журнала: 2025, Номер 15(2), С. 148 - 148

Опубликована: Фев. 4, 2025

With unique photochemical properties, graphitic carbon nitride (g-C3N4) has gained significant attention for application in photocatalytic degradation of a wide range organic pollutants. However, its performance is limited by the rapid electron–hole recombination and relatively weak redox capability. Substantial progress been made preparation g-C3N4-based photocatalysts with enhanced activity. This review summarizes recent advances strategies to improve activity their Morphology control, doping, functionalization, metal deposition, dye sensitization, defect engineering, construction heterojunctions can be used g-C3N4 through promoting charge carrier separation, reducing bandgap, suppressing recombination. Furthermore, oxidants, such as hydrogen peroxide persulfate, coupled enhance generation reactive oxygen species boost Precise control over structure during synthesis process remains challenge, further improvements are required photocatalyst stability mineralization rates More research development effort needed address existing challenges, refine design activity, promote practical pollutant degradation.
