General description

Freezing temperature lowerings of aqueous solutions of sodium dihydrogencitrate has been investigated[1].

Application

Sodium dihydrogencitrate has been employed:
  • as reductant and stabilizer during the synthesis of Fe3O4 Pt core/shell particles[2]
  • in characterization of carbon-based electrode materials as cathode in half-cell configuration[3]
  • in electrochemical reduction of proton at carbon fiber electrode in the presence and absence of Pt nanoparticles[4]
