Abstract
Novel graphitic carbon nitride (g-C3N4) coated TiO2nanocomposites were prepared by a facile and cost-effective solid-state method by thermal treatment of the mixture of urea and commercial TiO2. Because the C3N4was dispersed and coated on the TiO2nanoparticles, the as-prepared g-C3N4/TiO2nanocomposites showed enhanced absorption and photocatalytic properties in visible light region. The as-prepared g-C3N4coated TiO2nanocomposites under 450°C exhibited efficient visible light photocatalytic activity for degradation of aqueous MB due to the increased visible light absorption and enhanced MB adsorption. The g-C3N4coated TiO2nanocomposites would have wide applications in both environmental remediation and solar energy conversion.
