Embodiment 1

[0030] 17.1mg (0.1mmol) 2-methyl-4,5 imidazole dicarboxylic acid, 34.6mg (0.15mmol) cadmium acetate Cd (CH 3 COO) 2 Add to 4mL of water, then add 4mL of ethanol, and mix well. After the resulting mixture was sealed, it was subjected to solvothermal reaction at 130°C. After 36 hours of reaction, it was cooled to room temperature at a rate of 10°C per hour to obtain colorless blocky transparent crystals, which were washed with methanol and dried naturally to obtain Single crystal samples of metal cadmium complexes.

Embodiment 2

[0032] 17.1mg (0.1mmol) 2-methyl-4,5 imidazole dicarboxylic acid, 46.0mg (0.2mmol) cadmium acetate Cd (CH 3 COO) 2 Add to 4mL of water, then add 4mL of ethanol, and mix well. After the resulting mixture was sealed, it was subjected to solvothermal reaction at 140°C. After 36 hours of reaction, it was cooled to room temperature at a rate of 10°C per hour to obtain colorless blocky transparent crystals, which were washed with methanol and dried naturally to obtain Single crystal samples of metal cadmium complexes.

Embodiment 3

[0034] 17.1mg (0.1mmol) 2-methyl-4,5 imidazole dicarboxylic acid, 46.0mg (0.2mmol) cadmium acetate Cd (CH 3 COO) 2 Add to 4mL of water, then add 4mL of ethanol, and mix well. After the resulting mixture was sealed, it was subjected to solvothermal reaction at 130°C. After 40 hours of reaction, it was cooled to room temperature at a rate of 10°C per hour to obtain colorless blocky transparent crystals, which were washed with methanol and dried naturally to obtain Single crystal samples of metal cadmium complexes.

Abstract

The invention discloses a metal cadmium compound. A 2-methyl-4, 5 imidazole dicarboxylic acid (MIDA) ligand and cadmium acetate Cd(CH3COO)2 are synthesized under solvent thermal conditions to obtain the metal cadmium compound, a molecular structural formula of the prepared metal cadmium compound is C24H17Cd3N6O16.33, wherein Cd is a divalent metal cadmium ion, and the MIDA ligand and the cadmium ion form a three-dimensional net structure through carboxyl oxygen atoms and imidazole nitrogen atoms of 2-methyl-4, 5 imidazole dicarboxylic acid. A form of metal cadmium compound is of a structure ofa solid crystal, and crystallization of the crystal is a hexagonal system and an R-3 space group. The preparation method of the metal cadmium compound includes the step: performing reaction on 2-methyl-4,5 imidazole dicarboxylic acid and cadmium acetate Cd(CH3COO)2 under the solvent thermal conditions to obtain colorless and transparent massive crystals. The prepared metal cadmium compound can serve as a photocatalyst, and carbon dioxide is changed into carbon monoxide. A preparation process is simple and easy to implement, the purity and the yield of a product are high, and the metal cadmiumcompound has good application prospects in the aspect of photocatalytic conversion of the carbon dioxide.

Description

technical field [0001] The invention relates to the technical field of metal coordination compound functional materials, in particular to a metal cadmium complex and its preparation method and application. Background technique [0002] Combustion of fossil fuels such as oil releases large amounts of CO 2 , causing many environmental problems such as global warming. will CO 2 The concept of reducing to chemical fuel can fundamentally solve the problem of CO 2 Climate and environmental problems caused by emissions. To achieve this, visible light can be used to catalytically reduce CO 2 , to obtain new fuels such as CO and methane. Searching for efficient photocatalysts is the key to solving CO 2 The key to restoration. Traditional carbon dioxide photocatalysts generally use expensive noble metal complexes. However, there are few reports on the application of cadmium complexes in the photocatalytic reduction of carbon dioxide. Therefore, the preparation of this new typ...
