Abstract
Well-crystalline CeO(2-x) nanotubes are synthesized via a mild hydrothermal reaction route using cerium nitrate and ammonium hydroxide as reactants. The CeO(2-x) nanotubes have the same structure as the bulk CeO2 but larger lattice parameter. The measurement of the ratio of M5/M4 edge shows the valence reduction of cerium ions for the CeO(2-x) nanotubes.
摘要
通过使用硝酸铈和氢氧化铵作为反应物，采用温和的水热反应路线合成了结晶良好的CeO(2-x)纳米管。CeO(2-x)纳米管与块状CeO2具有相同的结构，但晶格参数更大。M5/M4边缘比率的测量表明CeO(2-x)纳米管中铈离子的价态降低。
