Graphitic carbon nitride(g-C3N4)-based photocatalysts for dye removal: Current status

Sustainable Chemistry for the Environment, Journal Year: 2024, Volume and Issue: 7, P. 100141 - 100141

Published: Aug. 7, 2024

Water contamination is a global concern as result of growing industrialization and urbanization. Dye waste produced by numerous industries pollutes the water, so dye-based wastewater major alarm for animals, human health, environment. The elimination these dye contaminants from water supplies currently critical significant due to dyes' toxicity on humans, livestock, plants. To remove/degrade dyes, various methods have been investigated, including extraction, absorption, membrane separation, coagulation, adsorption, biological treatment, advanced oxidation process (AOPs). Graphitic carbon nitride (g-C3N4), captivating formed polymer, has transformed an intriguing issue in AOP science because its metal-free advantages high sensitivity light. Accordingly, when AOPs are joined with g-C3N4, superb degradation occurred. This paper overviewed g-C3N4-based discussed removal. synergist effectiveness mechanisms behind catalytic activity catalysts broadly discussed. In meantime, impacts pH, temperature, dissolved oxygen, initial concentration, catalyst dosage, scavengers reaction carried out illustrated.

Photocatalytic processes offer promising solutions for environmental remediation and clean energy production, yet their efficiency under the visible light spectrum remains a significant challenge. Here, we report novel silver–graphene (Ag-G) modified TiO2 (Ag-G-TiO2) nanocomposite photocatalyst that demonstrates remarkably enhanced photocatalytic activity both dye wastewater degradation hydrogen production UV irradiation. Through comprehensive characterization performance analysis, reveal Ag-G modification narrows bandgap from 3.12 eV to 1.79 eV, enabling efficient absorption. The achieves peak rate of 191 μmolesg−1h−1 in deionized (DI) water solution light, significantly outperforming unmodified TiO2. Intriguingly, observe an inverse relationship between rates with tap versus DI water, highlighting critical role composition processes. This work not only advances understanding fundamental mechanisms but also presents solar-driven production. Ag-G-TiO2 nanocomposite’s across spectra, coupled its dual functionality evolution, represents step towards addressing challenges treatment sustainable generation. Our findings highlight complex interplay absorption reaction conditions, offering new insights optimizing systems. research paves way developing more versatile photocatalysts, potentially contributing global transition technologies circular economy waste management
