In this paper, parallel flaw precipitation method has been employed to fabricate nanostructured Bi2O3. It is found that the surface parameters, bandgap, the photoinduced charge separation rate and photocatalytic performance of Bi2O3 have a strong dependence on the pH value of precipitation reaction.The prepared photocatalysts were characterized by BET, XRD, UV-Vis diffuse reflectance and surface photovoltage spectroscopy (SPS). The results show that Bi2O3 prepared under pH value10.0 exhibits the best photocatalytic activity among the experimented compositions. The results of further experiments show that surface parameters, bandgap, the photoinduced charge separation rate all play an important role in promotion of photocatalytic activity of Bi2O3 prepared under pH value 10.0.

In this paper, ZnO photocatalyst was prepared by sol-gel method with the assistance of ionic liquid (IL). The structure, morphology and the photoinduced charge separation rate of the photocatalyst prepared (IL-ZnO) were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM) and surface photovoltage spectroscopy (SPS), respectively. The results reveal that ionic liquid enhances the photoinduced charge separation rate. The activity of ZnO for photocatalytic decolorization of methyl orange (MO) solution was evaluated. The results show that the photocatalytic activity of IL-ZnO is higher than that of ZnO.

A review of photoinduced charge separation of organic molecules in microporous and mesoporous materials is presented. In particular, the photoionization of N-alkylphenothiazine (PCn), N,N,N′,N′-tetramethylbenzidine (TMB), and porphyrin in microporous materials, such as zeolites, aluminophosphates (AlPOs), silicoaluminophosphates (SAPOs), and mesoporous materials, such as MCM-41, MCM-48, and SBA-15, is discussed.
