چکیده مقاله:
Perovskite-based photocatalysts are of significant interest in the field of photocatalysis.Barium zirconate (BaZrO3) has been extensively studied and widely used in variousapplications, such as thermal barrier coating material for aerospace industries. It has distinctive physical and chemical properties such as high thermal stability, excellent chemical durability, low coefficient of thermal expansion, and good structural compatibility [1]. Barium zirconate (BaZrO3) with ideal perovskite structure is a value-added material for the refractory industry as well as a good substrate for the manufacturing of high temperature superconductors due to its structural compatibility and chemical inertia [2]. Ceramic was characterized by Energy dispersive X-ray analysis (EDX), FT-IR, SEM, UVvis spectroscopy and X-ray diffraction (XRD). XRD analysis and SEM reveal pureperovskite phase structure and uniform grain size. Parameters such as concentration of substrate, amount of photocatalyst, pH of the solution, temperature of reaction medium and time of irradiation of light for photocatalysis degradation of Eosin Y (EY) were investigated. Ceramic show the maximum adsorption at high pH hence the photodegradation also found maximum at high pH.
