摘要：Silver chromate (Ag2CrO4) nanocrystals were prepared by ultrasonic synthesis, template and hydrothermal methods. The visible-light photocatalytic activity of Ag2CrO4 nanocrystals was investigated. The products synthesised by ultrasonic synthesis method had the highest activity and photodegraded the organic dye completely within only 8min. The products synthesised by the other two methods had the same degradation time of about 42min. The photocatalytic mechanism of the Ag2CrO4 catalyst was studied. This work offered a new and feasible scheme that can dispose the chromium-containing waste water and can produce a new visible-light catalyst at the same time, which can degrade the organic pollutant in the waste water.
