Synthesis of TiO_2−xN_y/Ag‐PbMoO₄ Composite and Their Photocatalytic Activity Under Simulated Solar Light Irradiation

Abstract

TiO2−xNy/Ag‐PbMoO4 composite were synthesized by sonochemical method. The results revealed that the band‐gap energy absorption edge of TiO2−xNy/Ag‐PbMoO4 composite was shifted to a longer wavelength as compared to TiO2, TiO2−xNy, PbMoO4, and Ag‐PbMoO4. The TiO2−xNy/Ag‐PbMoO4 composite showed the enhanced photocatalytic activity for degradation of indigo carmine dye (ICD) under simulated solar light irradiation. The TiO2−xNy/Ag‐PbMoO4 composite exhibited the highest percentage (95.4%) of degradation of ICD and the highest reaction rate constant (0.0244 min−1) in 2 h. The results suggested that a good combination of Ag and TiO2−xNy nanoparticles has great influence on the photocatalytic behavior of PbMoO4.

Visible‐light‐driven photocatalytic degradation using Mn‐doped SrMoO4 nanoparticles

“…In order to improve photocatalytic performance, various efforts have been made, including rare earth element doping, loading with Ag metal and fabricating composites with other oxide semiconductors . Among those methods, doping with heteroatoms will create impurity levels in the forbidden band, hindering the recombination of photogenerated electron–hole pairs and consequently promoting the photocatalytic activity.…”

Enhanced Visible Light Photocatalytic Activity of Curcumin‐Sensitized Perovskite Bi0.5Na0.5TiO3 for Rhodamine 6G Degradation

“…However, photocatalytic activity of TiO 2 is limited to ultraviolet light (UV) region due to a large band gap. Alternative ways, such as doping (B, C, and N) and surface sensitization, have been proven to improve photocatalytic efficiency and to extend its response for the visible light range by altering the optical band gap and absorption . Exploring new material systems is essential to improve the efficiency of visible light photocatalysis.…”
