A preparation method of the visible-light photocatalyst Bi2WO6 nano-powder is characterized by comprising the steps as follows:(1) the selection of raw materials;(2) bismuth nitrate Bi(NO33 question mark 5H2O is added into a citric acid solution to obtain the citric acid solution containing white sediment;(3) EDTA is added into ammonia water which is then added dropwise with the citric acid solution containing the Bi(NO3)3 question mark 5H2O so to obtain a solution of bismuth;(4) the solution of bismuth is added with (NH4)6W7O24 question mark 6H2O solution to form a precursor solution which is then stirred, dried, coked, cooled and ground to obtain decarburized powder;(5) the decarburized powder is roasted for 2h to 4h under 450 DEG C to 550 DEG C to obtain the visible-light photocatalyst Bi2WO6 nano-powder.
