摘要
用水热法合成得到纳米TiO2／MnTiO3复合材料，并用X射线衍射（XRD）、紫外-可见光谱（UV-VIS DRS）、拉曼光谱、表面光电压能谱对制得的样品进行表征。结果表明：复合材料的衍射峰在48．1°（101）处表现出明显的红移，在可见光和紫外区域的吸收均有所改变，拉曼光谱在619cm^-1处出现明显的振动峰值，表面光电压强度有所下降，但表现出明显的红移。
In this work, nano-TiO2/MnTiO3 composites with different molar ratios of MnTiO3 and TiO2 are synthesized by hydro-thermal method. Then samples are characterized by X-ray powder diffraction（XRD）, ultraviole-visible diffuse reflectance spectra（UV-VIS DRS）,Raman spectra and surface photovohage spectra（SPS）,respectively. As a result, the diffraction peak 48. 1°（101） shows an obvious red shift and Raman spectra shows an obvious vibration peak at 619cm^-1. The absorption of the region changes in both ultraviolet and visible light. Photovoltage on the surface becomes weaker but also shows an obvious red shift.
