Abstract A perovskite catalyst was prepared and its microwave induced catalytic degradation of basic fuchsin (BF) dye wastewater performance was tested. The microwave catalytic technology and modern characterization technology were combined with environmental chemistry experimental teaching. The LaMO3 (M=Fe, Ni, Co, Cu, Mn) catalyst was prepared by sol-gel method. N2 adsorption-desorption instrument (BET), scanning electron microscopy (SEM), fourier transform infrared spectroscopy (FT-IR), X-ray photoelectron spectroscopy (XPS) and thermogravimetric analysis (TGA) were used to characterize the structure, morphology and microwave catalytic activity of the catalyst. The effects of the different B-site metal of perovskite on the microwave catalytic activity of BF were investigated by characterization data and performance test results. The mechanism of the catalytic reaction was further explored. This comprehensive design experiment will enable students to acquire the frontiers of the advanced oxidation technology, broadening their professional vision, and training their comprehensive thinking, scientific research spirit and innovation ability.
