Modulating high-index facets on anatase TiO2

Zhaoxia Ding, Meimei Zuo, Yaqin Yu, Chuanyong Jing, Zhen Zhou
The atomic arrangement of titanium and oxygen on crystalline anatase TiO2 formulates various facets, dominating the TiO2 surface chemistry. Due to its unique surface atomic structure, TiO2 exposing high-index facets has received great interests from a wide spectrum of science. Insights gained from the intricate nexus between morphological modulation of anatase TiO2 with distinct high-index facets and their related properties can expedite the rational fabrication of functional crystals. This review succinctly comb recent impressive progress on the manipulation of high-index facets of anatase TiO2, focusing on the comparison of surface energies. In addition, the rational synthesis and fascinating performances of both high-index terminated pristine anatase TiO2 and their modified surfaces are collectively discussed. Finally, the perspective of ongoing research on high-index bounded anatase TiO2 is addressed.
