Problems solved by technology

Due to the large C-H bond energy in saturated hydrocarbons, if severe conditions are used for oxidation, the selectivity of the product will be poor due to deep oxidation, but if the oxidation conditions are too mild, it cannot be oxidized or the conversion rate of the raw material is too low. Therefore, it is of great theoretical significance to study the selective oxidation of alkanes.

Embodiment 1

[0020] The organic ligand 5,15-bipyridine-10,20-di-p-carboxyphenyliron porphyrin (0.01 mmol) and ferric nitrate nonahydrate (0.01 mmol) were dissolved in 3 mL of N,N-dimethylformamide Mix well with 3mL of acetic acid, and seal in a vial. Crystals of MOFs were obtained via thermal reaction at 120 °C for 36 hours.

Embodiment 2

[0022] The organic ligand 5,15-bipyridine-10,20-di-p-carboxyphenyliron porphyrin (0.01 mmol) and ferric nitrate nonahydrate (0.02 mmol) were dissolved in 3.5 mL of N,N-dimethylformaldehyde Stir evenly in amide and 2 mL of acetic acid, and seal in a vial. Crystals of MOFs were obtained via thermal reaction at 100 °C for 48 hours.

Embodiment 3

[0024] The organic ligand 5,15-dipyridine-10,20-di-p-carboxyphenyliron porphyrin (0.01 mmol) and ferric nitrate nonahydrate (0.02 mmol) were dissolved in 4 mL of N,N-dimethylformamide Stir well with 3mL of acetic acid, seal in a vial. Crystals of MOFs were obtained via thermal reaction at 100 °C for 48 hours.

Abstract

The invention discloses a metal organic framework material of a Fe porphyrin ligand, a preparation method therefor and an application thereof, and belongs to the technical field of crystalline materials. A chemical formula of the Fe porphyrin ligand is FeL, wherein L is am organic ligand, namely 5, 15-bipyridine-10 and 20-dicarboxyphenyl ironporphyrin. In a closing condition, a crystal of the metal organic framework material is obtained by the organic ligand, namely 5, 15-bipyridine-10, 20-dicarboxyphenyl ironporphyrin and iron nitrate nonahydrate by virtue of thermal reaction in a solution of N,N-dimethylformamide and acetic acid. The metal organic framework material has an iron porphyrin catalytic property, and can be used for selective catalysis of cycloalkane.

Description

technical field [0001] The invention belongs to the technical field of crystalline materials, and the technology relates to a metal-organic coordination polymer material, in particular to a metal-organic framework material of Fe, a preparation method and an application thereof. Background technique [0002] Saturated hydrocarbons are easy to obtain and cheap, and their functionalization has great economic benefits. Therefore, the functionalization of saturated hydrocarbons through oxidation is a frontier topic that many chemists are very interested in. Due to the large C-H bond energy in saturated hydrocarbons, if severe oxidation conditions are used, the selectivity of the product will be poor due to deep oxidation, but if the oxidation conditions are too mild, it cannot be oxidized or the conversion rate of the raw material is too low. Therefore, it is of great theoretical significance to study the selective oxidation of alkanes. At the same time, alkane oxidation also ha...
