摘要
采用高温固相法合成了层状Bi2W2O9,随后通过酸化处理得到H2W2O7·nH2O。采用X射线衍射仪(XRD)、扫描电子显微镜(SEM)、红外光谱(IR)对产物进行了表征。结果表明,采用高温固相法可获得层状结构的Bi2W2O9,层间距1.2 nm。经酸交换后的H2W2O7.nH2O仍保持层状结构,但层间距略变小。
A layered compound Bi2W2O9 was synthesized by solid-state reaction at a high temperature. Then Bi2W2O9 was treated with hydrochloric acid. The compounds were characterized by XRD, SEM and IR. The results showed that the layered Bi2W2O9 could be obtained by solid-state reaction at a high temperature and its interlayer distance was 1.2 nm. After acid-exchanging, the layered structure was retained but the interlayer distance became shorter.
