Abstract

Graphitic carbon nitride (g-C₃N₄), a promising metal-free photocatalyst, shows a high thermal stability, excellent chemical stability, and great optical absorption of solar light. However, a short life of activated electron-hole pairs limits g-C₃N₄ in practical applications. In this work, Ag₂MoO₄ nanoparticles encapsulated in g-C₃N₄ (Ag₂MoO₄/g-C₃N₄) was synthesized with a facile in-situ precipitation method. A variety of characterization techniques were applied for analyzing the compositions, morphologies and optical properties of Ag₂MoO₄/g-C₃N₄. The band structure of Ag₂MoO₄ produces a synergistic effect with g-C₃N₄, which can efficiently increase solar light absorption and reduce the recombination rate of the photo-induced electron-hole pairs. Therefore, this hybrid catalyst presents a much higher photocatalytic activity for the degradation of various organic pollutants (bisphenol A, acyclovir, and methyl orange) and strong stability under both artifical and real sunlight, which is promising for practical application.
