纳米结构TiO 2（TiO 2）的电位依赖型光吸收光谱主要由两个过程（带填充和插层）来解释。在弱积累条件下，由电子占据的表面和导带状态占主导地位，与被吸附的质子或阳离子补偿的积累的电荷。然而，在强积累条件下，质子或阳离子的嵌入可能会发生与一小部分的累积的电子被定位在Ti-IV网站。(C)2000年电化学学会。S0013-4651（99）11-019-X。All rights reserved.
The potential-dependent optical-absorption spectroscopy of nanostructured TiO2 (anatase) is most fully accounted for by two processes, band-filling and intercalation. Under weak-accumulation conditions, occupation of surface and conduction-band states by electrons dominates with the accumulated charge being compensated by adsorbed protons or cations. Under strong-accumulation conditions, however, intercalation of protons or cations may take place with a fraction of the accumulated electrons being localized at Ti-IV sites.
