High-efficiency visible-light-driven oxidation of primary C–H bonds in toluene over a CsPbBr3 perovskite supported by hierarchical TiO2 nanoflakes

A hierarchical CsPbBr 3 /TiO 2 heterostructure is fabricated by in-situ growth of CsPbBr 3 nanoparticles on the surface of TiO 2 nanoflowers assembled by 2D nanoflake subunits for toluene oxidation, which efficiently produces aldehydes and alcohols under visible light.
