Fig.4-1Crystalstructures of TiO2(a)Anatase;(b) Rutile TiO2的光催化机理如下[2]:如图4-2所示,半导体材料的特征是具有一个填满电子的低能价带(valenceband)和空的高能导带(conductionband),价带和导带之间存在禁带(或称带隙bandgap)。当用能量等于或大于禁带宽度的光照射半导体时,价带上的电子(e-)被激发跃迁至...
A single crystal of anatase TiO 2 was studied by Raman spectroscopy at quasi-hydrostatic pressures up to 70 GPa. The crystallinity of the sample shortens the pressure range of the transition to an α-PbO 2 structure to between 4.5 and 7 GPa. The resulting polycrystalline sample then transforms...

Different structures of anatase TiO2 from nanoparticles-based spheres to aggregated nanoparticles have been successfully fabricated by a simple refluxing method using a prepared titanium glycolate precursor. Variations in crystal phase, morphology, and size of TiO2 nanostructures were investigated by powder ...
