摘要

TiO₂是众所周知的功能性无机半导体光催化材料,于紫外光下在解决当今面临的特殊环境问题方面具有优异的性能。然而,TiO₂由于其宽带隙(3.1～3.4eV),只能吸收一小部分的太阳光光谱(λ<387nm),因此,为了将TiO₂的光学响应转移到可见光范围内,提高光催化活性,改善物质与光催化剂之间的相互作用以及活性位点等问题仍然是需要解决的挑战。简要介绍了TiO₂基材料的研究现状;重点阐述了MOF衍生功能性TiO₂的合成及光催化应用。总结了在改善Ti基新型光催化复合材料结构性能等方面的有效途径和方法,并分析了现存问题和挑战。

Abstract

TiO₂ is a well-known functional inorganic semiconductor photocatalytic material with excellent performance under UV light in solving particular environmental problems faced today.However,TiO₂ can only absorb a small proportion of the solar spectrum (λ<387nm) due to its wide bandgap (E_g=3.1～3.4eV).Therefore,the issues of improving interaction between the materials and the photocatalyst as well as the accessibility of the active sites are still challenges needed to be addressed in order to transfer the optical response of titanium dioxide into the visible range and improve the photocatalytic activity.Here in,the research status of TiO₂-based materials was briefly introduced and the synthesis and photocatalytic application of MOF-derived functionalized TiO₂ were emphasized.Finally,the effective ways and methods to improve the structural properties of Ti-based photocatalytic composites were summarized,and the existing problems and challenges were analyzed.
