Photocatalytic Properties of Immobilised Graphitic Carbon Nitride on the Alumina Substrate

Textile industries significantly impact the contamination of wastewater. Conventional wastewater treatment methods consider most common pollutants; however, they are very expensive and commonly produce toxic by-products. In scientific community, advanced oxidation processes appear to be appealing, a majority published work considers heterogeneous photocatalysis for degradation various chemicals. For convenience, reaction is performed directly in water environment. this work, metal-free graphitic carbon nitride (g-C3N4) was prepared through simple thermal method using urea as precursor. Prepared g-C3N4 deposited on surface alumina ceramic ring by dip-coating ethylene glycol binder. The ring, substrate, slip casting method. Photocatalytic properties immobilised were used methylene blue model pollutant under simulated solar light irradiation. photocatalyst characterised XRD, FTIR, UV-Vis DRS, TGA, BET SEM/EDX analyses. photocatalytic MB from an aqueous solution found increase with increasing irradiation time. It that convenient largescale environmental applications because whole setup cheap, nontoxic, easy operate offers reusability high removal rate after three consecutive cycles.
