Embodiment 1

[0033] Example 1, Synthesis of Metal Organic Framework (PCN-222(Co) or PCN-224(Co)).

[0034] Synthesis of PCN-222(Co): Dissolve benzoic acid (1.25 g) and zirconium oxychloride (50 mg) in 10 mLDEF, heat at 100 °C for 1 hour, and phenylcobalt porphyrin carboxylate (50 mg) in the above solution, ultrasonically dissolved, heated at 120 °C for 12 h, washed with DMF and acetone, and 50 mg of purple-red solid was obtained. Yield 50%.

[0035] Such as figure 1 As shown, the scanning electron microscope (SEM) images of the as-prepared samples showed that the microscopic morphology of PCN-222(Co) was rod-like micron-scale crystals. The crystal structure of PCN-222(Co) ( figure 2) was verified by X-ray powder diffraction pattern (PXRD). N2 adsorption data ( image 3 ) shows that PCN-222(Co) is a mesoporous material with a pore size of 3.6 nm.

Abstract

The invention belongs to the field of catalysis of porous composite materials, and particularly relates to a mesoporous metal-organic framework multi-center catalyst as well as a preparation method and application thereof. Zirconium-oxygen clusters are used as nodes, and tetracarboxylic acid metalloporphyrin is used as an organic chain to construct a rod-like (hexagonal) or cubic crystal; the metal organic framework material is formed by self-assembling zirconium oxygen clusters and tetracarboxylic acid metalloporphyrin at a certain temperature through coordination; the metal organic frameworkmaterial has a large pore size, a high specific surface area and excellent thermal stability and chemical stability. Through a post-modification method, stannous chloride can be loaded on the zirconium oxide cluster to obtain the mesoporous metal organic framework multi-catalytic center catalyst. The catalyst material can efficiently convert glucose into 2,5-furandicarboxylic acid under a photo-thermal condition.

Description

technical field [0001] The invention belongs to the technical field of porous composite material catalysis, and in particular relates to a mesoporous metal-organic framework multi-center catalyst, a preparation method thereof and an application in biomass conversion. Background technique [0002] As a non-renewable energy source, fossil fuels are expected to be exploited within 50-100 years, which seriously threatens global energy security. Therefore, finding green and recyclable alternatives to traditional fossil fuels has become the key to solving this problem. Biomass, as the largest recyclable carbon resource on earth, has the potential to solve this problem. Biomass is an important resource composed of organic matter such as cellulose, hemicellulose, and lignin. It has the characteristics of a wide range of sources, green, renewable, and contains a variety of oxygen-containing functional groups. Every year, 1.7×10 11 tons of biomass. It can meet the needs of human s...
