Sol-gel auto combustion synthesis, characterization, and application of TbFeMnO nanostructures as an effective photocatalyst for the discoloration of organic dye contaminants in wastewater.

In this study, the auto-combustion sol-gel method was used to prepare novel TbFeMnO (TFMO) double perovskite nanoparticles. Chemical and natural fuels were used to achieve these particles with appropriate size. The resulting particles were examined X-ray powder diffraction (XRD) and scanning electron microscopy (SEM) techniques.

Green sol-gel auto combustion synthesis and characterization of double perovskite TbZnMnO nanoparticles and a brief study of photocatalytic activity.

In this work, new double perovskite TbZnMnO nanoparticles were successfully synthesized by a sol-gel auto combustion method. To synthesize these nanoparticles, three known sugars, lactose, fructose, and maltose, and liquorice powder, which contains quantities of sugar and other organic compounds, were used as fuel. Images obtained from Scanning Electron Microscopy (SEM) analysis implied that maltose-based nanoparticles are homogenous and less in particle size.
