Anatase TiO2 hierarchical nanospheres with enhanced photocatalytic activity for degrading methyl orange　

Anatase TiO2 hierarchical nanospheres were synthesized through a simple way combining dealloying and hydrothermal methods. The photocatalytic activity of the obtained products and Degussa P25 were evaluated by the degradation of methyl orange (MO) aqueous solution at different initial pH values and concentrations.
