Application

Sodium sulfate can be used to prepare aqueous solutions for various electrochemical reactions such as direct nitrate electroreduction and to study carrier transfer in Mn-oxide/Nb: SrTiO3 photoelectrode. It can also be used as a solvent to fabricate heat storage materials such as silica gel–sodium sulfate composites.
