Abstract

g-C3N4/TiO2 composite photocatalyst was prepared by a facile solid-phase method of directly heating industrial metatitanate and urea, and characterized. Its photocatalytic activity under visible light was evaluated by degradation rate of NO. The results showed that the composite prepared at the mass ratio of urea to metatitanate 2 and calcining at 450℃ for 1 h was the best. While the composite was put under a 12 W LED visible light source, the degradation rate of NO could reach 48.40%.

Key words： g-C3N4/TiO2 composite; calcination; photocatalysis; NO; metatitanate; urea
