Abstract

Sb2Se3 can readily form long, 1D rod-shaped structures due to the intrinsic properties of orthorhombic Sb2Se3 crystals. Herein, short, 1D rod-shaped Sb2Se3 was synthesized by a facile mixed solvothermal method with tartaric acid (TA) assistance, and the synthetic mechanism is illustrated. Different sizes of 1D Sb2Se3 nanorods could be achieved by controlling the reaction temperature and using THF as a solvent to increase the reaction pressure. The formation of long, 1D rod-shaped Sb2Se3 when sodium tartrate was added instead of tartaric acid was explained by the coordination and dissociation equilibrium of antimony potassium tartrate. The effect of different amounts of TA on Sb2Se3 morphology was interpreted based on the precipitation–dissolution equilibrium of Sb2Se3. This study provides an effective method to control the sizes of Sb2Se3 nanorods.
