Preparation method and application of tetragonal NaV2O5⋅H2O nanosheet-like powder
A preparation method of a tetragonal NaV2O5.H2O nanosheet-like powder includes steps of: (S1) simultaneously adding NaVO3 and Na2S.9H2O into deionized water, and then magnetically stirring, and obtaining a black turbid solution; (S2) sealing after putting the black turbid solution into an inner lining of a reaction kettle, fixing the sealed inner lining in an outer lining of the reaction kettle, placing the reaction kettle into a homogeneous reactor, and then performing a hydrothermal reaction; and (S3) after completing the hydrothermal reaction, naturally cooling the reaction kettle to the room temperature, and then alternately cleaning through water and alcohol, and then collecting a product, drying the product, and finally obtaining the tetragonal NaV2O5.H2O nanosheet-like powder with a thickness in a range of 30-60 nm and a single crystal structure grown along a (002) crystal orientation.
