Abstract
Visible‐light‐responsive material based on Rhodium doped on titanium dispersed on dealuminated clinoptilolite (TiO2/HCP) was synthesized via a combination of the sol‐gel method and photoreductive deposition technique. The photocatalyst surface characterization, structural and optical properties were investigated by X‐ray diffraction (XRD), scanning electron microscopy (SEM), energy‐dispersive X‐ray analysis (EDAX), Fourier transform infrared spectroscopy (FTIR), thermal gravimetric analysis (TGA), and UV‐visible spectra (UV‐VIS). Doping TiO2/HCP with Rh imparts a red shifting of the absorption band into the visible light region according to UV‐VIS. The prepared composite materials were evaluated for their photocatalytic activities on pentachlorophenol (PCP) degradation under sunlight irradiation. The Rhodium doped TiO2/HCP exhibited enhanced photocatalytic activity and can be considered as a potential photocatalyst in wastewater treatment.
