Abstract

In this article, we report on a controllable synthesis of superhydrophobic Sb2O3 microcrystals via a solvothermal method assisted with the soluble inorganic Na2WO4 salt. Morphologies of the final products depend on the amount of the OH ions adsorbed on Sb2O3 nanoplates. By varying the amount of NaOH, the octahedral Sb2O3 can be switched to microcrystals or microspindles. Reaction and formation mechanisms of Sb2O3 were also proposed, which may also benefit synthesis of other metal oxides with controllable morphology. Additionally, after modified by (Heptadecafluoro-1,1,2,2-tetradecyl) trimethoxysilane, the as-synthesized octahedral Sb2O3 microcrystals and Sb2O3 microspindles show superhydrophobic and excellent anticorrosion properties in acidic and basic circumstances.
