Synthesis of a novel and stable g-C3N4–Ag3PO4 hybrid nanocomposite photocatalyst and study of the photocatalytic activity under visible light irradiation
Abstract
A facile and reproducible template free in situ precipitation method has been developed for the synthesis of Ag<sub>3</sub>PO<sub>4</sub> nanoparticles on the surface of a g-C3N4 photocatalyst at room temperature. The g-C<sub>3</sub>N<sub>4</sub>–Ag<sub>3</sub>PO<sub>4</sub> organic–inorganic hybrid nanocomposite photocatalysts were characterized by various techniques. TEM results show the in situ growth of finely distributed Ag<sub>3</sub>PO<sub>4</sub> nanoparticles on the surface of the g-C<sub>3</sub>N<sub>4</sub> sheet. The optimum photocatalytic activity of g-C<sub>3</sub>N<sub>4</sub>–Ag<sub>3</sub>PO<sub>4</sub> at 25 wt% of g-C<sub>3</sub>N<sub>4</sub> under visible light is almost 5 and 3.5 times higher than pure g-C<sub>3</sub>N<sub>4</sub> and Ag<sub>3</sub>PO<sub>4</sub> respectively. More attractively, the stability of Ag3PO4 was improved due to the in situ deposition of Ag<sub>3</sub>PO<sub>4</sub> nanoparticles on the surface of the g-C<sub>3</sub>N<sub>4</sub> sheet. The improved performance of the g-C<sub>3</sub>N<sub>4</sub>–Ag<sub>3</sub>PO<sub>4</sub> hybrid nanocomposite photocatalysts under visible light irradiation was induced by a synergistic effect, including high charge separation efficiency of the photoinduced electron–hole pair, the smaller particle size, relatively high surface area and the energy band structure. Interestingly, the heterostructured g-C<sub>3</sub>N<sub>4</sub>–Ag<sub>3</sub>PO<sub>4</sub> nanocomposite significantly reduces the use of the noble metal silver, thereby effectively reducing the cost of the Ag<sub>3</sub>PO<sub>4</sub> based photocatalyst.
