Nanobelts and nanocones of spinel Zn₂SnO₄

Abstract

Abstract One‐dimensional nanostructures of ternary oxide spinel, Zn 2 SnO 4 , have been prepared for the first time on a large scale via a reaction between element Sn, ZnS and Fe(NO) 3 at 1350 °C in a high‐temperature tube furnace. Scanning and transmission electron microscopic observations have confirmed that the as‐synthesized products consist of belt‐like and cone‐like single crystals. The dimensions of each nanobelt range from several hundred micrometers long, 100–500 nm wide, and several tens of nanometers thick. Formation mechanisms of these 1D nanostructures have been proposed.
