Benefits of technology

This patented technology allows creation of new types of molecules called Bimodals that have specific properties like pores size, shape, surface area, etc., which can be used to improve chemical reactions such as selective oxidation processes (SOR). These Bimods also allow for more precise control over their structures during production process compared to existing methods.

Problems solved by technology

This patents describes various methods for preparing special types of carboxylated pyridazole/ferrocanoimides called phthorods, which exhibits excellent characteristics like optically excited electronics, magnetic sensitivity, hydrothermal conductance, and reversible electrochromicity. These techniques allow us to efficiently attach these carriages onto surfaces while maintaining stability during operation.

Embodiment 1

[0034] Will K 5 [SiW 11 o 39 Ru(H 2 O)]·10H 2 O (70.0mg, 0.02mmol), Cu(NO 3 ) 2 ·3H 2 O (30.4mg, 0.12mmol) and 4,4′-bipyridine (19.3mg, 0.12mmol) were dissolved in a mixed solution of water (5.0mL) and acetonitrile (3.0mL), and mixed with 1mol·L –1 HAc adjusted the pH value of the solution to 4.4. After stirring for 12 hours, the above mixed solution was placed in an oven at 120°C. After reacting for 80 hours, it was cooled to room temperature, and brown-black columnar crystals were produced. After washing and drying, the target material POM / MOFs was obtained. (Catalyst Cu-BPY1), the yield is about 52%.

Abstract

The invention relates to the technical field of photocatalytic materials, and relates to a preparation method and an application of bimetallic photocatalytic functional POM/MOFs. Bimetallic photocatalytic functional POM/MOF target materials with a porous structure are prepared through a hydrothermal synthesis technology or a layered diffusion technology with polyoxometalate POM as a functional group, L as a connection ligand and Cu<2+>, Co<2+> or Fe<2+> in a transition metal salt Tm as nodes, and the target materials POM/MOFs are applied in a functional photocatalytic carbon- carbon coupling reaction. The preparation method has the advantages of simple synthetic steps, easy operation, low energy consumption and high yield, and the obtained functional materials have the advantages of stable chemical properties, and easy large-area popularization and application. The MOF photocatalytic materials have a large specific surface area, have a very good conversion rate and reusability under the irritation of a 18W energy saving lamp when the use amount is 6/1000 of the amount of a substrate, and are suitable for the needs of large-scale industrial production.
