Reduction of V4+ from V5+ using polymer as a surfactant for electrochemical applications
International Journal of Electrochemical Science, 2010 Vanadium dioxide nanowires and nanobelts were synthesized from vanadium pentoxide xerogel through a hydrothermal process. V5+ was reduced to V4+ by a polyblend of poly(vinyl pyrrolidone) (PVP) and poly(vinyl alcohol)(PVA), and by poly(vinyl alcohol)(PVA).
