摘要:
采用机械化学法,以SnCl2、Na2CO3为反应物,以NaCl为稀释剂合成SnO2纳米晶,采用TEM、XRD等方法对制备的SnO2纳米晶进行表征,并分析了球磨时间、稀释剂的用量及热处理温度对SnO2 纳米晶晶粒尺寸的影响.研究结果表明增加球磨时间和稀释剂的用量可以有效降低SnO2纳米晶的晶粒尺寸,利用该法制备的SnO2纳米晶粒径均匀,较优条件下晶粒尺寸可达7 nm.
Abstract:
Pure tin oxide (SnO2) nanocrystal was successfully prepared by a mechanochemical method,using SnCl2 and Na2CO3 as reagents while NaCl as diluent.The samples were characterized by transmission electron microscopy (TEM) and X-ray diffraction analysis (XRD).The effect of the milling time,the diluent NaCl content and the heat-treatment temperature on SnO2 nanocrystal size was investigated.Experimental results show that increasing the milling time and the NaCl diluent content can effectively reduce the nanocrystal size of SnO2.The product prepared in this way is uniform in size and the nanocrystal size can reach a minimum 7nm.
