Abstract Scope |
Recent research at the National Renewable Energy Laboratory has shown the potential of V2O5 to exhibit useful properties such as tunable chemical stoichiometry, structural phases, and redox properties for electronic materials applications. This work aims to explore the chemistry of a SnCl2 treatment of V2O5 to allow for the tuning and control of optoelectronic properties. We find that a fine control of oxidation state of the layered alpha phase of V2O5 nanoparticles is possible through tuning both the concentration and duration of the SnCl2 treatment. We also show the SnCl2 treatment reduces V2O5, resulting in Sn incorporation and formation of mixed valence states, V4+ and V5+. This work provides a foundational understanding of the SnCl2 treatment chemistry that will help to continue investigations into the incredible potential that Sn doping may have in the advancement of next generation electronic materials. |
