Microwave Synthesis and Photocatalysis of Nano-TiO2 Mix-crystals
Abstract:
With TiCl4 and urea as the raw materials,the mix-crystals of rutile and anatase TiO2 were prepared at 100℃ by means of microwave irradiation method.The effect of pH on the ratio of the nanometer TiO2 mix- crystal was discussed.The crystal structure was determined by XRD.TEM indicated that the TiO2 was spherical particles,and the average diameter of the particles was 15 nm.The photocatalytic experiment showed that the mix-crystal material had better photocatalytic activity than the singleness TiO2.The compound could completely degrade the blue dye in 50 min under the sunlight.
