摘要：

Of the various forms of TiO2 (anatase, rutile, and brookite), anatase is reported to be the best photocatalysts. High-temperature stable anatase TiO2 photocatalyst is required for antibacterial applications in building materials. Hysteretic effect of phase transformation in two-dimensional pure TiO2 is observed. The transformation from anatase to rutile phase varies with a large temperature range (400-1000 degrees C). The delayed phase transformation of 2D anatase TiO2 results from the synergetic effect of its own anomalous phase evolution and 2D morphologic structure. (C) 2018 Elsevier B.V. All rights reserved.
