Controllable synthesis of nanostructured BaSO4 and BaSO3 crystals on the basis of DMSO oxidation chemistry

Author affiliations

Abstract

A simple and novel SO2 release method for the synthesis of controllable nanostructured BaSO4 and BaSO3 crystals was developed based on the oxidation of HSO3 to SO42− by dimethyl sulfoxide (DMSO) in a binary system of triethylene glycol (TEG) + DMSO. The binary system was successfully re-used for SO2 absorption and production of BaSO3 crystals at least three times. Aggregation and self-assembly mechanisms for the preparation of BaSO4 and BaSO3 crystals were proposed. This controllable synthesis strategy for BaSO4 and BaSO3 crystals has offered an alternative way for the comprehensive utilization of SO2, and provided a scientific foundation for the development of DMSO oxidation chemistry.
