中文摘要：
通过爆轰H2、O2和SnCl4的混合气体来制备纳米SnO2是一种新的纳米SnO2的合成方法。通过XRD、TEM、HRTEM和纳米激光粒度仪对其晶型、形貌和粒径进行了表征，总结了初始压力对产物的影响。结果表明，合成的纳米SnO2为纯净的金红石相，且晶粒不存在缺陷。随着初始压力的提高，SnO2的晶粒粒径减小，但颗粒尺寸却变大，颗粒呈球形，出现团聚，分散性变差。
英文摘要：
SnO2 nanoparticles prepared by detonation the mixed gas of hydrogen, oxygen and tin tetraehloride was a now method. Its polymorphs, morphology and particle size were characteried by means of XRD, TEM, HRTEM and zetasizer nano and summarized the influence of the initial pressure on the product. The results showed that the synthesized nano-tin dioxide was pure rutile phase, and a grain does not exist. With the im- provement of the initial pressure, the grain size of the tin dioxide was reduced, but the particle size was larger, the particles are spherical and appear reunion, dispersion variation.
