preparation example Construction

[0036] According to the present invention, the synthesis method of the silver-containing polyacid-based metal organic framework crystalline material comprises:

[0037] Provide a kind of mixed solution, described mixed solution contains silver source, polyacid source and sulfur-containing organic ligand and water;

[0038] adjusting the pH of the mixed solution to 1-3, preferably 1.5-2, and performing hydrothermal crystallization;

[0039] The mixture obtained by hydrothermal crystallization was subjected to solid-liquid separation, and the obtained solid phase was dried.

[0040] In the present invention, Ag ions have high affinity to S, O and N donors in the ligand, and have multiple different coordination numbers in the coordination polymer. Therefore, Ag ions can adopt different coordination geometries and coordination numbers to coordinate with the sulfur-containing organic ligands, for example, to form two-dimensional (2D) metal-organic layers by Ag-N, Ag-O and Ag-S.

[0068] This example is used to illustrate the synthesis of the silver-containing polyacid-based metal-organic framework crystalline material provided by the present invention.

[0069] Ag 8 (mttz) 4 (H 2 O)[PW V W VI 11 o 40 ]·H 2 Synthesis of O:

[0070] AgNO 3 (1.0 mmol), H 3 PW 12 o 40 12H 2 O (0.055 mmol) and Hmttz (3.0 mmol) were dissolved in 7 mL of distilled water and stirred for 30 minutes. Then, with 1M HNO 3 The pH of the mixture was adjusted to 1.8 with aqueous solution and sealed in a 10 mL Teflon-lined autoclave. React at 120°C for 5 days under autogenous pressure. Then it was naturally cooled to room temperature to obtain a red block crystal, which was designated as compound 1. Wash with deionized water, then dry in air at 60 °C for 8 h. The yield based on W is 36% (the mass of tungsten in the product accounts for the percentage of the total mass of tungsten fed).

Description

technical field [0001] The invention relates to the field of catalytic materials, in particular to a silver-containing polyacid-based metal organic framework crystalline material, a synthesis method and application thereof, and a catalytic oxidation method of cycloolefins. Background technique [0002] Due to the good selectivity and mild reaction conditions of photocatalytic technology, photocatalytic technology has become a global research hotspot, and has attracted more and more people's attention in energy development and environmental governance. [0003] Currently, the epoxidation of olefins is an important route for the production and industrial applications of numerous chemicals. For example, the selective oxidation of cis-cyclooctenes for the synthesis of drugs, pesticides and polyesters. Selective oxidation of cis-cyclooctene is often difficult, especially under catalytic conditions, because the oxidation product of cis-cyclooctene is not a single product, and pos...
