Abstract

The invention discloses a preparation method of a transition metal ion Ni<2+> doped phosphate material. The transition metal ion Ni<2+> doped phosphate material is LaPO4 which is prepared from 2% Tb<3+> and x% Ni<2+>. The preparation method comprises the following steps that (1) a certain amount of lanthanum nitrate, nickel nitrate, terbium nitrate and ammonium dihydrogen phosphate are weighed forlater use; (2) lanthanum nitrate is taken and dissolved in deionized water and stirred to be uniform; and then terbium nitrate is added and stirred to be uniform; (3) nickel nitrate is added into theproduct obtained in the previous step and then stirred to be uniform; (4) ammonium dihydrogen phosphate is added into the product obtained in the previous step and then stirred to be uniform by usinga magnetic stirrer; and then the obtained product is placed in a reaction still to react for 9-12 hours; and (5) the product obtained in the previous step is cooled to be at the room temperature, andthen the deionized water and absolute ethyl alcohol are adopted to wet and wash the product alternately; and precipitation is collected by adopting a centrifugal machine, then the collected precipitation is dried and ground to be powder, and the transition metal ion Ni<2+> doped phosphate material is obtained. The preparation method is simple, and beneficial for achieving industrialized production.
