Embodiment Construction

[0009] We choose BiI 3 , 2-aminobenzothiazole is reaction raw material, adopts the mixed solution of ethanol and hydroiodic acid as reaction solvent, obtains inorganic-organic hybrid (Habtz) BiI under solvothermal condition 4 orange blocky single crystal. We determined the crystal structure of this bismuth-iodide hybrid material. The Bi atoms in the structure adopt a six-coordinated octahedral structure, and the adjacent (BiI 6 ) octahedrons are formed by common-edge connections (BiI 4 ) – anion chain. In situ protonation of the amino N atom in 2-aminobenzothiazole (Habtz) + Cation to balance the negative charge of the bismuth iodide anion chain.

[0010] The preparation of the bismuth-iodine hybrid material provided by the present invention is obtained by self-assembly of inorganic bismuth iodide and diaminobenzothiazole under solvothermal conditions, and the reaction solvent is a mixed solution of ethanol and hydroiodic acid, and the material preparation method is simp...

Abstract

The invention relates to synthesis of a bismuth iodine hybrid material and application to preparation of a BiOI nano-sheet, and aims to synthesize the bismuth iodine hybrid material, wherein the bismuth iodine hybrid material can be directly applied to hydrolysis to prepare the BiOI nano-sheet. A bismuth iodine based hybrid (Habtz)BiI4 is prepared by taking bismuth iodide and 2-aminobenzothiazoleas reaction raw materials and taking mixed liquid of ethanol and hydroiodic acid as a reactant and a solvent and under the solvothermal condition, wherein the abtz is 2-aminobenzothiazole. The bismuthiodine hybrid material is simple to prepare, the raw materials are low in price and the yield is high. The hybrid material serving as a precursor can be hydrolyzed rapidly without adding other reaction raw materials in distilled water and without adjusting the pH value of the reaction, so that simple and efficient preparation of the BiOI nano-sheet is realized.

Description

technical field [0001] The invention relates to a hybrid material, in particular to a bismuth iodine hybrid material (Habtz) BiI 4 The synthesis and application of hydrolysis to prepare BiOI nanosheets, where abtz = 2-aminobenzothiazole. Background technique [0002] Inorganic-organic hybrids are a class of compounds formed by the self-assembly of organic components and inorganic components at the molecular level. Because the organic components can be flexibly matched and selected, the structure of the hybrid material is very rich, and to a certain extent control the structure and performance. The choice of organic cations in hybrid materials will greatly affect the water stability of the prepared hybrid materials. Generally speaking, hybrids prepared with hydrophilic organic cations have weaker water stability. On the contrary, hybrids prepared with hydrophobic organic cations The prepared hybrid has strong water stability. Inorganic BiOI is a new type of semiconductor m...
