摘　　要：TiO2以稳定性高、成本低廉等诸多优势在早期光催化研究中备受青睐。然而,TiO2光催化剂的可见光响应程度低、量子效率低等问题,使得光催化领域对TiO2提出了更高的要求。本文围绕着二氧化钛基光催化材料,从晶面调控,表面等离子体共振及石墨烯复合三个方面入手,总结了在设计和合成光催化剂方面取得的创新性研究成果,最后基于结构设计、合成工艺优化以及新材料探索的角度对新型二氧化钛基光催化材料提出展望。Advanced TiO2-based photocatalysts with novel stability,low cost,and nontoxicity properties are benchmark materials that have been pursued for their high solar-energy conversion efficiency.However,the photocatalytic efficiency is affected by the degree of light absorption,quantum efficiency.In this review,recent researches and developments on TiO2 photocatalysts were summarized and introduced by three methods,namely modulation on morphology and crystal habit,surface plasmon enhanced light absorption,and graphene/TiO2 composite structures.Finally,some challenges are proposed with regards to structure design,modification of synthetic methods and material selection.
