Abstract：
Porous nanocrystalline Ln2Ti2O7 (Ln = Nd, Gd, Er) was prepared by a facile self-propagating combustion method using metal nitrates (Ln(NO3)3 (Ln = Nd, Gd, Er), TiO(NO 3)2) and glycine. The photocatalytic activity of Ln 2Ti2O7 (Ln = Nd, Gd, Er) was evaluated by the photocatalytic degradation of methyl orange (MO). The results showed that the photocatalytic activity of Ln2Ti2O7 (Ln = Gd, Er) with cubic pyrochlore structure was higher than that of Nd 2Ti2O7 with monoclinic perovskite structure and Gd2Ti2O7 showed the best photocatalytic activity. The different photocatalytic activities observed for Ln 2Ti2O7 (Ln = Nd, Gd, Er) could be related to its different crystal structures and Ln 4f shells. © 2014 Published by Elsevier B.V.
