Embodiment 1

[0025] A preparation method of ordered mesoporous polymer loaded metal phthalocyanine photocatalyst, the steps are:

[0026] (1) Take 5 g of FDU-14, 15 mL of chloromethyl ether, 0.5 g of ZnCl 2 at 10 o C for 3 h, filtered after the reaction, washed with deionized water until neutral, and then washed the obtained sample with 60 mL of acetone for 3 times, at 100 o Dried at C, the chloromethylated mesoporous polymer was FDU-14-CH 2 Cl.

[0027] (2) Take 5 g of FDU-14-CH obtained in step (1) 2 Add 40 mL of N,N-dimethylformamide (DMF) to Cl, add 0.4 g of zinc phthalocyanine, stir and swell at room temperature for 6 h, then add 2 g of ZnCl 2 Stir for 1 h, gradually increase the temperature to 80 o C, react for 2h, then raise the temperature to 110 o C was reacted for 6 h, and the filtered product was fully washed with water and acetone, respectively. The metal phthalocyanine photocatalyst FDU-14-ZnPc supported by ordered mesoporous polymer was obtained by vacuum drying.

Abstract

The invention discloses a photocatalyst of an ordered mesoporous polymer loading with metal phthalocyanine and a preparation method of the photocatalyst, belonging to the technical field of chemical catalysts and synthesis of the chemical catalysts. The photocatalyst of the ordered mesoporous polymer loading with metal phthalocyanine is composed of a carrier and metal phthalocyanine loaded on the carrier; and the carrier is a chloromethylation FDU-type ordered mesoporous polymer prepared through a chloromethylation functional reaction, wherein the weight percent of metal phthalocyanine in the photocatalyst of the ordered mesoporous polymer loading with metal phthalocyanine is 0.2-1.2; and the rest is the chloromethylation FDU-type ordered mesoporous polymer. According to the invention, the photocatalyst has double functions of absorbing and photo-catalyzing, and possesses advantages of the ordered mesoporous polymer and the metal phthalocyanine; the metal phthalocyanine molecules are restricted in highly ordered mesoporous channels and in a monomolecular dispersing state; therefore, the aggregation of the metal phthalocyanine molecules is inhibited; and the photocatalytic activity of the metal phthalocyanine molecules is improved.

Description

technical field [0001] The invention belongs to the technical field of chemical catalysts and their synthesis, and more specifically relates to an ordered mesoporous polymer-loaded metal phthalocyanine photocatalyst and a preparation method thereof. Background technique [0002] Metal phthalocyanine compounds (MPcs) have a strong π-π* transition in the visible light region and have good visible light catalytic activity. They can be used to sensitize visible light to degrade pollutants in water. The reaction mechanism is close to the biodegradation mechanism and has high efficiency. , energy saving, no secondary pollution and other advantages. However, metal phthalocyanine molecules are easy to aggregate in water, and the excited state energy of the metal phthalocyanine in the aggregated state is offset by the unexcited metal phthalocyanine molecules, resulting in a greatly reduced photocatalytic activity. The bimolecular aggregation of metal phthalocyanine reduces the photoc...
