摘要：
Hollow TiO2 nanocages with rubik-like structure were synthesized via a combined hydrolysis/hydrothermal method. Firstly, highly uniform Cu2O nanocubes covered by TiO2 layer were prepared by hydrothermal hydrolysis of (NH4)(2)TiF6 following by reducing copper-citrate complex with ascorbic acid. The Cu2O core templates could be easily removed in dilute HCl solution to form a hollow rubik-like structure. The obtained TiO2 nanocages show promising efficiency in the photocatalytic degradation of phenol pollutions. (C) 2012 Elsevier B.V. All rights reserved.
