The selective oxidation of toluene and its derivatives is extremely important in the chemical industry.The use of photocatalysis in organic synthesis has attracted considerable attention among synthetic chemists because of its “green” environmental characteristics. In this study, nanoscale Bi₂WO₆ with a flower-like morphology was found to be a highly efficient photocatalyst in the catalytic oxidation of toluene and its derivatives using O₂ as the oxidant. The loading of Pd nanoparticles as a cocatalyst onto the flower-like Bi₂WO₆ was found to produce a significant enhancement in the catalytic activity. Mechanistic investigation showed that the superior performance of Pd/Bi₂WO₆ could be attributed to the improvement of both the reductive and oxidative abilities of Bi₂WO₆by the loading of the cocatalyst.
