Method for preparing cerous phosphate nano wire

The invention is suitable for the technical field of nano materials, and provides a method for preparing a cerous phosphate nano wire. The method comprises the following steps of: preparing mixed liquor containing Ce3+ saline solution and PO43- saline solution; adjusting the pH value of the mixed liquor to 0.8 to 1.5; stirring the mixed liquor for 0.3 to 1.5 hours; and ageing the mixed liquor in water bath at the temperature of 90 to 95 DEG C under ambient pressure for more than 2 hours so as to obtain a hexagonal crystal cerous phosphate nano wire. The method for preparing the cerous phosphate nano wire can be carried out by a simple and low-cost device, so the production cost is lowered greatly, and industrial production is convenient to realize; and a template agent is not required to be added in the preparing process, so environmental impact caused by waste liquid is avoided.
