Abstract

Light rare earth (La, Ce, Pr) oxides with 3D superstructure are a kind of particularly interesting materials because of their unique optical, electronic, magnetic, and catalytic properties arising from the confinement of the 4f electrons. Here, we report a rapid and simple electrodeposition methodology for the assembly of three-dimensional (3D) superstructures of La2O3, CeO2, and Pr2O3 nanobelts using the nitrates based electrolytes with NH4Ac, and KCl as additives. The removal efficiencies of Congo red solution for La2O3, CeO2, and Pr2O3 nano superstructures can reach 68%, 76% and 71% in dark. But CeO2 show better removal efficiency than La2O3 and Pr2O3 under light irradiation.
