Green, sustainable and massive synthesis of sodium vanadate nanowires toward industrialization

Abstract

One-dimensional (1D) layered materials combine the advantages of layered materials and 1D nanomaterials, which has attracted intense interest not only in the academic research but also in the industrial application. Layered sodium vanadate nanowires have received incremental attention due to the high capacity and enhanced electrical conductivity for promising advanced energy storage and conversion. However, the mass production of these 1D layered vanadium vanadates (1D NVO) are still of great challenge and the further scalable application in energy storage and conversion systems are hampered. Herein, we developed a facile, non-hydrothermal, green synthesis strategy for scalable, mass production of layered vanadium vanadate nanowires and their assemblies such as membranes, blocks, grains, powders toward industrial scale. It will pave a way for the industrial production of 1D inorganic materials and give a new insight into the fabrication of nanostructured materials beyond commercialized 1D/2D nanomaterials including carbon nanotubes (CNT) and layered double hydroxides (LDH).
