TiO2MxOy heterostructures (M=Co, Cu, or Ru) have been synthesized via facile hydrothermal route. The products have been characterized using powder x-ray diffraction (XRD), scanning electron microscopy(SEM), energy-dispersive powder X-ray spectroscopy (EDX), and UV-visible diffusive reflectance spectroscopy (UV-Vis DRS). Solar driven photocatalytic activity carried out through the degradation of 4-chlorophenol (4-CP) under natural sunlight irradiation. The effects of chemical composition, band gap, and charge carrier transport pathway have been investigated and established Z-scheme charge carrier transport pathway. It is found that the charge carriers transport pathway plays a more important role than band gap and light absorption in the photocatalysis process.

Keywords: TiO2 -MxOy heterostructures; Solar driven photocatalyst; Charge carrier transport pathway; Z-scheme.
