Embodiment 1

[0027] A chemical grafting method prepares aminocobalt phthalocyanine / carbon nanotube composite catalyst, the preparation steps are as follows:

[0028] (1) Preparation of 1,8,15,22-tetranitrocobalt phthalocyanine

[0029] Weigh CoCl on an electronic balance 2 ·6H 2 O4.0mmol, 3-nitrophthalonitrile 16.0mmol, measure 100mL n-pentanol and DBU4mL with a measuring cylinder, heat the above-mentioned substances at 130°C under reflux and stir for 6h under the condition of nitrogen protection, then cool, filter with suction, and Wash the filter cake of the needle-shaped product with anhydrous methanol until the filtrate is colorless, dry the filter cake and grind it finely, then use 500 mL of 1mol / L HCl and NaOH solutions to boil for 1 hour, cool, centrifuge, dry, Grind dark blue 1,8,15,22-tetranitrocobalt phthalocyanine powder;

[0030] (2) Preparation of 1,8,15,22-tetraaminocobalt phthalocyanine

[0031] Put 0.36g of 1,8,15,22-tetranitrocobalt phthalocyanine obtained in step (1) ...

Abstract

The invention relates to the technical field of carbon nano tube composite catalyst grafting, in particular to a chemical grafting method for preparing an amidogen cobalt-phthalocyanine / carbon nano tube composite catalyst. The chemical grafting method comprises the four steps of 1,8,15,22-tetranitro cobalt-phthalocyanine preparation, 1,8,15,22-four-amidogen cobalt-phthalocyanine preparation, carbon nano tube pretreatment and composite catalyst preparation. According to the technical scheme, the amidogen cobalt-phthalocyanine / carbon nano tube composite catalyst is prepared, selected raw materials are wide in source, the preparation method is simple, aftertreatment is easy, and industrial production is facilitated.

Description

technical field [0001] The invention relates to the technical field of carbon nanotube composite catalyst grafting, in particular to a chemical grafting method for preparing an aminocobalt phthalocyanine / carbon nanotube composite catalyst. Background technique [0002] Since Calvin et al first used phthalocyanine and metal copper phthalocyanine complexes to catalyze the hydrogen exchange reaction in 1963, people have carried out extensive and in-depth research on the synthesis, structure and catalytic performance of metal phthalocyanine complexes. So far, people have synthesized more than 50 kinds of metal phthalocyanine complexes, and made them into homogeneous, heterogeneous and simulated enzyme catalysts, which are used to catalyze dozens of types of organic reactions. These organic reactions include hydrogen exchange reactions, hydrogenation reactions, reduction reactions of nitrogen oxides and acetylene, decomposition reactions of hydroperoxides, hydrogen peroxide and f...
