A high yield one-pot aqueous synthesis of crystalline SnO2 nanoparticles

Abstract A high temperature thermal treatment after precipitation from an aqueous solution is usually required to reach crystalline SnO 2 nanoparticles but this treatment generates a grain growth (up to 40 nm). Moreover, the yield is generally low ( 2 nanoparticles is described. The synthesis is performed at 100 °C under reflux: it exhibits a reaction yield over 90% and the particles are crystallized with a size of 4–6 nm.
