柠檬酸溶解-热解法合成纳米晶SnO2粉体   总被引:4,自引:0,他引:4  
The SnO2 nanocrystaline powders were synthesized by citric acid dissolution-pyrolysis method. The medium products were analyzed by FTIR. The products were characterized by TG-DTA, XRD, TEM, SEM etc. The results showed that the Sn was coordinated with aconitase acid during the dissolution. The SnO2 particles prepared by this method were with a mean size of 5~10 nm. The calcined products presented lacunose micro-arc structure, thus favoring the application as gas-sensitive materials.  相似文献
