The invention discloses a preparation method of bismuth selenite nanoscale, which belongs to the technical field of the preparation of functional materials. The concrete method is: firstly, sodium selenite and bismuth nitrate mixed evenly, the selenium and bismuth nitrate mixed powders in the corundum tube reaction vessel high temperature area and low temperature area of alumina corundum tube sheet is arranged on the reaction container, and sealing the reaction vessel, the high temperature zone is heated to 1000 to 1200 DEG C and low temperature district heating to 100 - 200 c, holding 1 ~ 3H, the surface of alumina containing white sediments; then the alumina slice is fixed in the reaction vessel, the sodium selenite, bismuth nitrate mixed with water into a reaction container and sealing, to charge oxygen into the reaction vessel, at temperature 300 to 500 DEG C, holding 24 ~ 72h. The invention adopts the two step reaction process, and the preparation process is simple and easy to control. The obtained bismuth selenate nanobelts have good application prospects in the fields of optics, catalysis and adsorption.
