Gram-scale synthesis of ultrasmall SnO2nanocrystals with an excellent electrochemical performance

Abstract

The gram-scale synthesis of ultrasmall SnO₂ nanocrystals has been successfully realized via a solvothermal process, during which the solvent used plays an important role in inhibiting the growth and aggregation of the nanocrystals. When investigating their electrochemical behaviour, the nanocrystal electrode shows an excellent performance in capacity retention and a better rate capacity.
