金红石型TiO_2(011)晶面的表面化学研究进展

A Review on Surface Chemistry of Rutile TiO_2(011) Surface

综述了采用高分辨扫描隧道显微镜(STM)等表面技术和密度泛函理论(DFT)计算等手段对TiO2(011)晶面的表面化学研究的进展,重点介绍了(011)面的表面结构组成、乙酸分子的吸附及诱导重构现象、水分子的吸附及产生的吸附氢原子的迁移和反应等方面的研究成果,揭示了TiO2表面结构与其化学性质的相互关系,为在原子尺度上理解TiO2催化材料的作用机理创造条件。

The progress of recent research on the surface chemistry of TiO2（011） by means of high-resolution scanning ttmneling microscopy（STM） and density function theory（DFT） calculation was reviewed. The surface configuration of restructure TiO2（011） surface, surface restructuring by interacting with acetic acid molecules, hydrogen adsorption and reactions on the surface were discussed. An atomic scale insight was presented to understand how the surface structures, orientations, electronic structures and adsorption properties of TiO2（011） surface affect its activities.
