摘　　要：TiO2半导体材料由于具有催化活性高、成本低廉且化学性质稳定等优点,在环境治理及能源转化领域受到广泛关注。然而TiO2本身禁带宽度较大,仅在紫外光范围内具有较高的催化活性,且电子-空穴对的再复合率较高,导致其对于太阳光的利用率较低。如何提高TiO2半导体材料对于太阳光的利用率并促进电子-空穴对的快速分离成为当前的研究热点。从TiO2纳米材料微观结构调控以及负载改性方式两方面综述了其最新研究进展,以期对进一步改善TiO2基纳米材料的光催化性能提供一定的指导意义。Due to the advantages of high catalytic activity,low cost and stable chemical properties,TiO2 semiconductor materials have attracted extensive attention in the field of environmental governance and energy conversion.However,TiO2itself has a wide band gap and high catalytic activity only in the range of UV light.Moreover,the recombination rate of electron-hole pairs is high,resulting in its low utilization rate of sunlight.How to improve the utilization rate of TiO2semiconductor materials for sunlight and promote the rapid separation of electronhole pairs has become a research hotspot in the current field.The latest research progress of TiO2nanomaterials was reviewed from the aspects of microstructure regulation and load modification methods,which had certain guiding significance for further improving the photocatalytic performance of TiO2nanomaterials.
