摘要：

Nano-sized TiO2/MoO3/carbon clusters composite material has been successfully obtained by the calcinations of a TiO(acac)(2)/MoO2(acac)(2)/epoxy resin complex under an oxygen atmosphere. 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 carbon clusters -> MoO3 -> carbon clusters -> TiO2.
