Novel Synthesis of Mixed Oxide Nanoparticles for Photocatalysis

Abstract

Vanadium oxo-alkoxy nanoparticles were prepared via sol-gel method, manually and in a chemical reactor with ultra-rapid micromixing. The materials were characterized by DLS, ATG-ATD, XRD and SEM methods. The influence of micromixing conditions on the particle size and growth kinetics was evaluated. Complementary, the preparation of mixed-oxide nanoparticles in presence of vanadium and titanium precursors was performed, showing a strong interaction between the two systems, promising for the fabrication of size- and compositional selective Ti-V oxide nanoparticles for photocatalysis.
