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.

The effects of reflux time and pH on the photocatalytic properties of N-TiO2photocatalyst were researched, which was prepared from titanium n-butoxide by reflux method at low temperature employing triethylamine as nitrogen source. The N-TiO2catalysts prepared prepared with reflux time for 6 h and 12 h shown better visible-light photocatalytic activity.
