Embodiment 1

[0013] Accurately weigh 0.005 mol of bismuth nitrate and grind it finely, then add 0.015 mol of sodium bicarbonate and grind it quickly. As the grinding progresses, the mixture changes from white viscous to white fine powder. Continue grinding for 40 minutes to ensure sufficient reaction The product was washed with water and ethanol, filtered with suction, and finally dried in air at room temperature for 1 hour to obtain bismuth oxycarbonate nanosheets.

Embodiment 2

[0015] Accurately weigh 0.005 mol of bismuth nitrate and grind it finely, then add 0.015 mol of ammonium carbonate and grind quickly. As the grinding progresses, the mixture changes from white viscous to white fine powder. Continue grinding for 40 minutes to ensure that the reaction is fully carried out , the product was washed with water and ethanol, filtered with suction, and finally dried in air at room temperature for 1 hour to obtain bismuth oxycarbonate nanosheets.

Embodiment 3

[0017] Accurately weigh 0.005 mol of bismuth nitrate and grind it finely, then add 0.015 mol of potassium bicarbonate and grind it quickly.

Description

technical field [0001] The invention relates to a method for synthesizing bismuth oxycarbonate nanosheets by solid phase chemical reaction at room temperature. Background technique [0002] Bismuth oxycarbonate (Bi 2 o 2 CO 3 ) has an orthorhombic crystal structure, and the unit cell parameters are a=3.865, b=3.865, c=13.675 Å, belonging to the Imm2 space group. It has a typical "sillen" structure, which is a layered structure similar to Aurivillius-type oxides, and [Bi in the layered structure 2 o 2 ] 2+ and [CO 3 ] 2- are arranged alternately. And the polyhedra formed by Bi-O in its crystal structure all show a large degree of distortion, which also makes the Bi-O bond relatively active and in an unstable state, and has broad application prospects in the field of functional materials. [0003] Nano Bi 2 o 2 CO 3 As a new type of semiconductor photocatalytic material, it exhibits good photocatalytic activity due to its layered structure and suitable band gap (3....
