采用水热离子交换法,以CoCl2和钼蓝H2MoO3纳米带为前驱物制备了含Co2+的正交相MoO3纳米带.测试结果表明,在Co2+掺入MoO3层间后基本没有改变前驱物纳米带的晶相和形貌;由Co2+掺入前后FTIR和XRD谱图的对比中还可证实,存在在钼蓝层间的H+不仅与[MoO6] 八面体中的端氧有较强的相互作用,而且还产生了新的晶面.
Co-embedded α-MoO3 (Co-MoO3) nanobelts were prepared using precursors CoCl2 and HxMoO3 nano-belts by hydrothermal and ion-exchangeable proceeding. The measurement results show that the crystalline phase and morphology of Co-MoO3 have not been changed yet after the Co2+ cations were embedded into the space between the two nearest-neighbored layers; by comparison of the FTIR spectra and XRD patterns for the two samples with and without the Co2+ cations,it can be also demonstrated that the H+ ions between the layers not only exist interaction with the oxygen atoms in MoO6, but also form new crystalline plane.
