Formation and Evolution of the High-Surface-Energy Facets of Anatase TiO2

The anatase TiO 2 single crystal exposed high-surface-energy facets have attracted much attention. However, the evolution mechanism and process of the high surface energy facets are still not clear. Here, based on the analysis of experimental results and theoretical calculation results, the evolution process and balanced coexistence for high-surface-energy TiO 2 facets, such as {001} and {110} facets, was well explicated. Thus, this work will help for better understanding and controlling of the morphology of metal oxide crystals with different facets.
