Urea assisted ceria nanocubes for efficient removal of malachite green organic dye from aqueous system

This study describes a simple, high-yield, rapid, and inexpensive route for the synthesis of cubic shape-like cerium oxide nanocubes (CeO(2) NCs) using different urea concentrations (0.5, 1.0, and 2.0 g) by the hydrothermal method. The synthesized nanocubes (NCs) are labeled as CeO(2) NCs-0.5, CeO(2...

Sumario:This study describes a simple, high-yield, rapid, and inexpensive route for the synthesis of cubic shape-like cerium oxide nanocubes (CeO(2) NCs) using different urea concentrations (0.5, 1.0, and 2.0 g) by the hydrothermal method. The synthesized nanocubes (NCs) are labeled as CeO(2) NCs-0.5, CeO(2) NCs-1.0, and CeO(2) NCs-2.0, corresponding to 0.5, 1.0, and 2.0 g of urea, respectively. The synthesized NCs were characterized by FT-IR, UV-visible, XRD, XPS, SEM and HR-TEM analysis. The synthesized NCs were cubic in shape with average sizes of 12, 12, and 13 nm for the CeO(2) NCs-0.5, CeO(2) NCs-1.0, and CeO(2) NCs-2.0, respectively, obtained by the XRD analysis. The catalytic activity of the CeO(2) NCs was studied for the purpose of obtaining the reduction of malachite green (MG) in the presence of sodium borohydride (NaBH(4)) at room temperature.
