通过微波处理MoCl5/ZrCl4/淀粉/石墨络合物，成功地制备了纳米MoO_3/碳团簇/ZrO_2复合材料。采用电感耦合等离子体(ICP)光谱、元素分析、X射线衍射仪(XRD)和透射电子显微镜(TEM)对复合材料进行了表征。测定了复合材料的紫外可见光谱(UV-Vis)、X射线光电子能谱(XPS)和电子自旋共振(ESR)谱。复合材料的电子自旋共振谱表明，它们具有可见光响应催化能力，其电子转移过程为MoO_3、→、碳团簇→、ZrO_2。
Nano-structured MoO3/carbon clusters/ZrO2composite material has been successfully obtained by the microwave-treatment of a MoCl5/ZrCl4/starch/graphite complex. The compositions of the resulting composite materials were determined using inductively coupled plasma (ICP) spectroscopy, elemental analysis, and surface characterization by X-ray diffraction (XRD) and transmission electron microscopy (TEM). The ultraviolet–visible (UV–vis), X-ray photoelectron spectra (XPS) and electron spin resonance (ESR) spectra of the composites were also measured. ESR spectra of the composite materials suggest that they have visible light-responsive catalytic ability with an electron transfer process of MoO3→carbon clusters→ZrO2.
