Embodiment approach

[0013] Realize the embodiment of the present invention as follows:

Embodiment approach 1

[0014] Embodiment 1 : 2 mmol 2-methylimidazole, 1 mmol Zn(OH) 2 and 0.5 mmol of CuCl 2 2H 2 O was added to 3 mL of anhydrous methanol, and then 15 mL of ammonia water was added to it, and the reaction was stirred at room temperature and normal pressure for 5 h. After the reaction was completed, the solid product was filtered through H 2 The mixed solution of O / MeOH (1:1 V / V) was washed three times and dried to obtain the desired 2+ ZIF-8 material, denoted as Cu 2+ / ZIF-8.

Embodiment approach 2

[0015] Implementation mode 2:2 mmol 2-methylimidazole, 4 mmol Zn(OH) 2 and 0.5 mmol of Co(CH 3 COO) 2 2H 2 O was added to 10 mL of anhydrous methanol, and then 20 mL of ammonia water was added to it, and the reaction was stirred at room temperature and normal pressure for 24 h. After the reaction was completed, the solid product was filtered through H 2 The mixed solution of O / MeOH (1:1 V / V) was washed three times and dried to obtain the desired Co-containing 2+ The ZIF-8 material, denoted as Co 2+ / ZIF-8.

Abstract

The invention discloses a preparation method for a metal complex functionalized ZIF-8 (zinc 2-methylimidazolate) material, which belongs to the scopes of physical chemistry and material chemistry. The preparation method is characterized by comprising the following steps of directly introducing the needed metal ions during synthesis for a zeolite-like imidazole framework material ZIF-8, then matching the metal ions supported by the zeolite-like imidazole framework material containing the needed metal ions with a selected ligand in certain conditions, so as to immobilize the metal complex in the zeolite-like imidazole framework material ZIF-8. According to the preparation method, a multi-phase supported catalyst can be prepared by virtue of the unique subject effect of ZIF-8, and a new way can be provided for functionalization for the ZIF-8 material and preparation for a novel functional material.

Description

technical field [0001] The preparation method of the metal complex functionalized ZIF-8 material of the present invention belongs to the category of physical chemistry and material chemistry, and specifically relates to directly introducing the required metal ions in the synthesis of the zeolite imidazole framework material ZIF-8, and then adding the required ZIF-8 of metal ions coordinates the supported metal ions with the selected ligand under certain conditions, thereby immobilizing the metal complexes in the ZIF-8 material. Background technique [0002] Metal complexes are excellent homogeneous catalysts, which have many advantages such as reactivity, high selectivity and mild reaction conditions, but have disadvantages such as difficult separation from products and non-recyclability. Immobilizing metal complexes on solid supports to achieve homogeneous catalytic heterogeneity is an effective way to solve these disadvantages, and it is also an important topic in green ch...
