TiO2/g-C3N4 Visible-Light-Driven Photocatalyst for Methylene Blue Decomposition

In this work, graphitic carbon nitride (g-C3N4)/titanium dioxide (TiO2) nanoparticles with heterostructures were synthesized in situ from a mixture of melamine and peroxo-titanium complexes calcination process. The TiO2 are well-dispersed on the g-C3N4 nanosheets. prepared TiO2/g-C3N4 composites have heterostructure excellent photocatalytic activity for decomposing methylene blue (MB) under visible light irradiation. as-obtained embroiled has much larger surface area than its components (66.7 6.6 m2·g?1 against 95.5–143.8 composite, respectively). It enhances separation photo-generated charge carriers. degradation MB was investigated aqueous heterogeneous suspensions. experimental kinetic data process follow pseudo-first-order model. Furthermore, retains high after four reaction cycles. addition to prompt removal color, photocatalyst can oxidize almost completely final oxidation products. pathway decomposition also addressed. Additionally, system employed eliminate other typical organic pigments, such as malachite green, methyl blue, red. material, remarkable dye degradability, is promising catalyst industrial textile treatment find applications light-harvesting systems.
