TiO2納米粒子的光催化活性與光伏響應(yīng)特性研究

We investigated the photovoltaic properties of series of TiO2 photocatalysts by means of SPS and found that the thresholds of TiO2 particles blue shift with their particle sizes decreasing and crystal phases changing from rutile TiO2 to anatase TiO2. Combining with the photodegradation activities of TiO2 on C7H16, it was concluded that the photocatalytic activities of TiO2 increase with their thresholds increasing,which can be explained using energy band theory. We also investigated the relationship beween the photovoltaic properties and photocatalytic activities of BTiO2 before and after photooxidation on C7H16, SO2 and C7H16+SO2, respectively and found adsorbates at the surface of TiO2 affect their photocatalytic activities and conduction types of surface layer.
