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?, 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 semiconductor photocatalytic material, it exhibits good photocatalytic activity due to its layered structure and suitable band gap (3.20eV). I...
