通过控制盐的水解和微波辐射制备出晶粒尺寸为 6～ 2 5nm的TiO2 、Fe/TiO2 粉体。对水解温度、陈化时间、微波辐射的影响进行研究 ,发现TiO2 水解温度在 70～ 80℃、Fe/TiO2 水解温度在 6 5℃时 ,晶粒尺寸较小 ,而室温陈化时间的长短对晶粒尺寸没有大的影响 ,样品未微波辐射与微波辐射的晶粒尺寸、热性质等存在明显不同。通过XRD、TG DSC、TEM对制得的纳米粉体进行了表征
The TiO2 and Fe / TiO2 powders with grain size of 6 ~ 25nm were prepared by controlling salt hydrolysis and microwave irradiation. The effects of hydrolysis temperature, aging time and microwave irradiation were studied. It was found that when the hydrolysis temperature of TiO2 is 70-80 ℃ and the hydrolysis temperature of Fe / TiO2 is 65 ℃, the grain size is small, and the length of aging time The grain size does not have a big effect, and there is a significant difference between the non-microwave radiation and the grain size and thermal properties of the microwave radiation. The prepared nano-powders were characterized by XRD, TG DSC and TEM
