Abstract :

MZrO3 (M = Pb, Cu and Cd) photocatalyst have been successfully synthesized by mechanochemical – solid state method with green chemistry approach. The synthesized photocatalysts were characterized for microstructural properties by various analytical investigative techniques like, Fourier transform infra red spectroscopy (FTIR), UV–visible diffused reflectance spectroscopy (UV–DRS), Barret, Joyner and Halenda (BJS–BET) surface area, Scanning electron microscopy (SEM), Energy dispersive spectrometer (EDS), Tunneling Electron microscopy (TEM) with Selective area electron diffraction (SAED) Electrical conductivity and Thermogravimetric analysis (TGA). The photocatalytic power of the sample was investigated systematically using direct black dye under different irradiation wavelengths. Solar light was employed as irradiation source showing that this type of structures could drive to plausible strategy for developing photocatalyst to degrade waste–water. The synthesized PbZrO3 , CdZrO3 and CuZrO3 shows orthorhombic pervoskite phase with BET surface area, surface area 49.49 m2 /g, 13.60 m2 /g, 20.22 m2 /g, respectively Photodegradation of direct black dye follows pseudo first order kinetic.
