TiO2-Based Heterostructure Containing g-C3N4 for an Effective Photocatalytic Treatment of a Textile Dye

Water pollution has become a serious environmental issue. The textile industries using dyes are considered to be one of the most polluting all industrial sectors. application solar-light semiconductor catalysts in wastewater treatment, among which TiO2 can prospective candidate, is limited by rapid recombination photogenerated charge carriers. To address these limitations, was tailored with graphitic carbon nitride (g-C3N4) develop heterostructure g-C3N4@TiO2. Herein, simple hydrothermal synthesis TiO2@g-C3N4 presented, titanium isopropoxide (TTIP) and urea as precursors. morphological optical properties structure g-C3N4, TiO2, prepared (with different wt.% up 32%), were analyzed various laboratory methods. photocatalytic activity studied through degradation methylene blue (MB) aqueous solution under UV-A simulated solar irradiation. results showed that amount g-C3N4 irradiation source important influences on efficiency MB removal Photocatalytic also examined realistic conditions, such natural sunlight environments. synthesized g-C3N4@TiO2 nanocomposite superior comparison pure thus promising new photocatalyst for real-life implementation. mechanism investigated scavengers electrons, holes, hydroxyl radicals find responsible species degradation.
