Preparation of nano-dispersed lithium niobate by mechanochemical route

Interaction in the system of lithium carbonate–niobium pentoxide during mechanochemical treatment in air and water has been studied. Prepared samples have been investigated with the help of DTA–TG, XRD, FTIR, Raman, and UV–Vis spectroscopy, adsorption–desorption of nitrogen and TEM. Activation of re...

Description
Summary:Interaction in the system of lithium carbonate–niobium pentoxide during mechanochemical treatment in air and water has been studied. Prepared samples have been investigated with the help of DTA–TG, XRD, FTIR, Raman, and UV–Vis spectroscopy, adsorption–desorption of nitrogen and TEM. Activation of reagents and direct mechanochemical synthesis are observed at 600–850 and 1,000 rpm, respectively. Lithium metaniobate samples prepared via milling possess high dispersity, defective structure, and improved photocatalytic activity, including under visible illumination.
