摘要:以硝酸铋和钨酸钠为反应物,在乙醇-水混合溶剂体系中反应生成钨酸铋纳米结构。通过调整乙醇和水的比例、反应温度、反应时间等参数,在溶剂热条件下可以直接生成钨酸铋中空纳米结构。实验结果表明,当醇水体积比为10∶1,溶剂热温度为100 ℃,反应时间为12 h时,制备的Bi2WO6纳米空心球粒度均匀,直径在30~50 nm,壳的厚度在10 nm左右。

Abstract:
Bi2WO6 nano-structures were synthesized in ethano-water mixed solvent with Bi(NO3)3 and Na2WO4 as reactants. Bi2WO6 hollow nano-structures can be prepared through solvothermal process by adjusting the ratio of ethanol to water, reaction temperature and reaction time. The results indicated that Bi2WO6 hollow nano-spheres with 30-50 nm in diameter and 10 nm in thickness could be synthesized when the ratio of ethanol to water was 10∶1, reaction temperature 100 ℃, and reaction time was 12 h.
