The invention discloses a BiOCOOH-Bi2O2CO3 compound photocatalyst and a preparation method thereof and belongs to the field of photocatalysis. The BiOCOOH-Bi2O2CO3 compound photocatalyst is mainly characterized in that a prepared BiOCOOH photocatalyst is taken as a raw material, the irradiation time is controlled under ultraviolet irradiation, and the BiOCOOH-Bi2O2CO3 compound photocatalyst with efficient photocatalytic activity can be obtained. The preparation method comprises preparation steps as follows: 1, preparation of BiOCOOH: bismuth nitrate pentahydrate is dissolved in a N,N-DMF (dimethylformamide) solution and stirred to be transparent, a certain amount of deionized water is added, mixed and stirred, a white suspension liquid is formed, the white suspension liquid is put in a reaction kettle for a reaction, and an obtained product is subjected to centrifugal separation, washed and dried; 2, a certain amount of prepared BiOCOOH is irradiated under ultraviolet light for 3-8 h, the product is washed several times with water and absolute ethyl alcohol and dried, and the BiOCOOH-Bi2O2CO3 compound photocatalyst is obtained. The method adopts a simple process and is low in cost, and the prepared BiOCOOH-Bi2O2CO3 compound photocatalyst has efficient visible-light catalytic activity. |
