Abstract

The invention belongs to the field of rare earth phosphate nanometer material, and relates to a method for synthesizing a monoclinic structured CePO4 nanometer material, in particular to a method for synthesizing a monoclinic structured CePO4 nanometer material by adopting low temperature, non-template and recyclable raw material H3PO4; Ce(NO3)3.6H2O is taken as a cerium source and dissolved in water, added with H3PO4 to lead the molar ratio of PO4<3->Ce<3+> in the reactant to be 800-300, stirred for 20-30min to cause thorough mixing, then the mixture is transferred into a hydrothermal reaction kettle, and allowed to react for 6-8h at 100-160 DEG C to obtain monoclinic structured CePO4 nanometer powder. The preparation method of the invention is simple, the equipment is simple, the synthesis temperature is low, the raw material H3PO4 is recyclable and cheap, and no expensive surfactant is needed as the template; the method is characterized by no use of organic solvent, no environmental pollution, energy saving, high conversion ratio, and being easy for industrialized production and the like, and has the advantages of effective reduction of the synthesis temperature and good repeatability, and the method is an ideal pollution-free process.
