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.
