A new microwave heating method for preparation of CaNiO3 photocatalyst material is described. The optimum preparation conditions are that the microwave power is 560W, the microwave heating time is 30min, the calcination temperature is 700℃ and the calcination time is 5h. The compound is measured by X-ray diffraction. In visible light and under the conditions of simulated fuel waste water, the photocatalytic properties of the catalyst material are studied. The results show that the photocatalytie material prepared by that microwave heating has a high photocatalytic performance of degradation, and the degeneration rate of the dye may reach 98%.
