主 题:Nanowires TiO2 Photocatalysis Degradation Photocurrent
摘 要:Titania nanowires(TiO2-NW)with tunable aspect ratios and morphologies were directly synthesized using a simple alcohol-thermal ***,ethanol and acetic acid were used as solvents and lithium ion was used as the capping agent to promote the conversion of titanium butoxide into *** morphologies and crystal phases of TiO2-NW were determined by the molar ratio of solvents and the content(mol%)of lithium *** band gap of TiO2-NW with pure anatase phase is slightly bigger than that of TiO2-NW with a mixture of anatase and rutile *** TiO2-NW could achieve effective decolorization of methyl blue(the decolorization rate is over 95%)after 35-min ultraviolet(UV)irradiation.
