摘　　要：采用水热法,以SnCl2·2H2O和草酸为原料,研究了水热温度、水热时间、PVP-K30和草酸用量对纳米二氧化锡粒度的影响,通过XRD和SEM对纳米二氧化锡的晶型、形貌进行了表征。结果表明,实验所得产物均为四方晶系球形纳米二氧化锡,改变水热温度,可制备出平均粒径在127.7~300.0 nm的纳米二氧化锡;改变水热时间可制备出平均粒径在72.1~180.0 nm的纳米二氧化锡;改变PVP-K30用量,可制备出平均粒径在59.7~180.0 nm的纳米二氧化锡;改变草酸用量,可制备出平均粒径在90.0~460.0 nm的纳米二氧化锡;纳米二氧化锡的粒径随着水热温度的升高和水热时间的延长而增大;随着PVP-K30和草酸用量的增加而减小。SnCl2·2H2O的用量0.116 g,PVP-K30用量1.1 g,草酸用量3.15 g,水热温度160℃,水热时间2 h下所制备的纳米二氧化锡的粒径为180.0 nm。The effects of hydrothermal temperature,hydrothermal time,PVP-K30 and oxalic acid dosage on the particle size of nano-tin dioxide were studied by hydrothermal method using SnCl 2·2H 2O and oxalic acid as raw materials.The crystal structure and morphology of nano-tin dioxide were characterized by XRD and SEM.The results show that the products are all tetragonal spherical nano-tin dioxide.Nano-tin dioxide with an average particle size range from 127.7~300.0 nm can be prepared by changing the hydrothermal temperature;nano-tin dioxide with an average particle size range from 72.1~180.0 nm can be prepared by changing the hydrothermal time;nano-tin dioxide with an average particle size range from 59.7~180.0 nm can be prepared by changing the amount of PVP-K30;nano-tin dioxide with an average particle size range from 90.0~460.0 nm can be prepared by changing the amount of oxalic acid;the particle size of nano-tin dioxide increases with the increase of hydrothermal temperature and hydrothermal time,and decreases with the increase of the amount of PVP-K30 and oxalic acid.SnCl 2·2H 2O dosage is 0.116 g,PVP-K30 dosage is 1.1 g,the oxalic acid is 3.15 g,the hydrothermal temperature is 160℃,hydrothermal time is 2 h,so the prepartion of nano-tin dioxide particle size is 180.0 nm。
