RETRACTED: Decahedral TiO2 with exposed facets: Synthesis, properties, photoactivity and applications

As an important metal oxide, titanium dioxide has been widely investigated because of its unique surface, electronic, and photocatalytic properties, which make this material applicable in many areas of science and technology ranging from adsorption, catalysis and photocatalysis to biomedicine, environmental monitoring and cleanup, energy conversion and storage, etc. The properties of anatase TiO 2 crystals are largely determined by external surfaces exposed. Since the breakthrough in synthesizing anatase TiO 2 single crystals with a large percentage of highly reactive (0 0 1) facets in 2008, many unusual properties and applications of these (0 0 1) facets dominant in anatase TiO 2 have been explored theoretically and experimentally, showing the industrial importance of this semiconductor material. Here we review the recent progress in synthesizing by various synthetic methods and photocatalytic activity TiO 2 with exposed crystal facets with different morphologies.
