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.

Applied Organometallic Chemistry, Год журнала: 2025, Номер 39(4)

Опубликована: Март 3, 2025

ABSTRACT The aim of this study is to prepare novel, efficient, economical, and environmentally friendly composites for treating the pollutants in wastewater. In study, sodium phthalocyanine cobalt sulfonate (CoSPc) composite was synthesized using (CoPc) liquid sulfur trioxide as raw materials, then CoSPc loaded on porous γ‐alumina (γ‐Al 2 O 3 ) through ultrasonic impregnation method first time. Fourier transform infrared spectroscopy (FT‐IR), X‐ray diffraction (XRD), scanning electron microscopy (SEM), ultraviolet visible (UV–Vis), N adsorption–desorption isotherms analysis were adopted analyze composite. Rhodamine B (RhB) model pollution used evaluate photocatalytic activity CoSPc/Al result showed that exhibited exceptional RhB degradation under potassium persulfate (PMS)‐assisted light illumination. Specifically, degraded by 95.5% within 12 min. Even after cycles, it manages degrade approximately 90% addition, only a very small amount PMS (0.01 mmol/L) can achieve excellent effects. conclusion, has great potential industrial application elimination organic dye

Fabrication of Two-Dimensional Bi2MoO6 Nanosheet-Decorated Bi2MoO6/Bi4O5Br2 Type II Heterojunction and the Enhanced Photocatalytic Degradation of Antibiotics

Inorganics, Год журнала: 2024, Номер 12(11), С. 289 - 289

Опубликована: Ноя. 4, 2024

This article successfully synthesized a series of Bi2MoO6/Bi4O5Br2 heterojunctions using two-step solvothermal method followed by calcination, and the photocatalytic activity degradation tetracycline hydrochloride (TC) was investigated. Compared with pure Bi4O5Br2 Bi2MoO6, exhibit higher activity, which can be attributed to heterostructures strong interfacial interaction, improving charge separation. The 2% heterojunction shows best under visible light irradiation, is 1.9 times 1.8 that Bi2MoO6 Bi4O5Br2, respectively. In addition, cyclic experiments have shown has high stability, efficiency only decreasing 3% after 5 cycles. From capture agent experiment ESR test, it seen ·O2− h+ are main active species. A possible mechanism irradiation proposed.
