Improved Photocatalytic and Electrochemical Performance of Hydrothermally Synthesized Mg2SnO4 Nanocubes and their Effect on Loading with Activated Carbon

Abstract

Highly crystalline Mg 2 SnO 4 nanocubes were successfully synthesized using a facile hydrothermal method. Further activated carbon was loaded with Mg 2 SnO 4 nanoparticles in order to enhance the photocatalytic performance. Photocatalytic performance of Mg 2 SnO 4 nanocubes and activated carbon loaded Mg 2 SnO 4 nanocomposites were examined by methyl green and methylene blue dye degradation under the exposure of UV light. However, results suggest that activated carbon loaded Mg 2 SnO 4 nanocomposites has significantly enhanced the photocatalytic performance over Mg 2 SnO 4 nanocubes. It is assumed that better photocatalytic activity is caused by the higher specific surface area of activated carbon loaded Mg 2 SnO 4 nanocomposites. Furthermore, cyclic voltammetry was used to analyze the electrochemical properties of the samples. Results indicate that activated carbon significantly enhanced the electrochemical properties of Mg 2 SnO 4 nanoparticles. Copyright © VBRI Press.
