Template-based growth of V2O5 nanorods by electrodeposition and/or sol electrophoresis

EMSL Project ID
5120

Abstract

 Template-based growth of single crystal V2O5 nanorods by either electrochemical or electrophoretic deposition was studied. Specifically, standard electrochemical deposition from VOSO4 solution, electrochemically induced deposition by local pH change of VO2+ solution, and electrophoretic deposition of nanoclusters in V2O5 sol were investigated. From each route, uniformly sized V2O5 nanorods about 10 μm in length were grown over large area with nearly unidirectional alignment, but with various extent of lateral shrinkage when fired at 500C. These grown V2O5 nanorods all have the same single-crystal structure, regardless of deposition method and initial solutions or sol used.
