One-step SDS-assisted hydrothermal synthesis and photoelectrochemical study of Ag4V2O7 nanorods decorated with Ag nanoparticles

Abstract

Ag/Ag₄V₂O₇ nanocomposites with Ag nanoparticles supported on Ag₄V₂O₇ nanorods have been synthesized with the assistance of sodium dodecyl sulfate (abbreviated to SDS) by a facile one-step hydrothermal reaction and exhibit high photoelectrochemical response. Ag₄V₂O₇ nanorods are pointed at both ends with an average width of ca. 200 nm. Ag nanoparticles are formed in situ on the surfaces of the Ag₄V₂O₇ nanorods. The crystal structures and morphologies of the samples are affected significantly by the SDS concentration and hydrothermal reaction time. The possible crystal growth process of Ag/Ag₄V₂O₇ nanocomposites induced by SDS has been discussed preliminarily.
