Abstract:
1. A method for synthesizing a bifunctional perovskite compound, comprising: dissolving respectively a lanthanum nitrate, a calcium nitrate, a cobalt nitrate and a iridium chloride in water to form an aqueous solution; mixing and agitating the plurality of aqueous solutions to form a mixture; preparing a saturated citric acid aqueous solution, wherein the saturated citric acid and a plurality of metal ions having the same moles; mixing the mixture and the saturated citric acid aqueous solution; heating the mixture and the saturated citric acid aqueous solution to form a metal sol; drying the metal sol; grinding the dry metal sol to obtain a precursor powder; heating the precursor powder; and cooling the precursor powder to prepare the perovskite compound.
