Preparation and photocatalytic activity of ZnCr-LDH
Original language description
Zn2CrCO3 LDH was prepared by coprecipitation and anionic exchange method. It was found that this type of LDH has photocatalytic activity. This sample was then calcined at different temperatures to obtain mixed oxides (especially ZnO which is known as a good photocatalyst) to increase the photocatalytic properties of prepared Zn2CrCO3 LDH. It was found that the best temperature of thermal treatment for application in photocatalysis is 600°C. The sample at 600°C was well crystalline and the rate of AO7 degradation was almost 2 times higher than for Zn2CrCO3 LDH without calcinations. It was proved that one of oxidating species are OH radicals. OH radicals were even produced with noncalcined ZnCr LDH, but in concentration more than 20 times lower than calcined sample with the same light irradiation (365 nm).
