Embodiment 1

[0024] (1) Pretreatment of attapulgite

[0025] Put 2g of attapulgite and 200ml of concentrated nitric acid into a 250ml three-necked flask at a temperature of 120°C, reflux and condense for 10h and naturally cool to room temperature to remove HNO 3 Clear night, then dilute with deionized water to remove HNO 3 The clear solution was diluted repeatedly, then filtered with a Buchner funnel, and finally dried in an oven.

[0026] (2) Preparation of [3-2-(N-ethylanilino)ethoxy]zinc phthalocyanine

[0027] Pour 2.60g (15mmol) of 3-nitrophthalonitrile and 4.96g (30mmol) of 2-(N-ethylanilino)ethanol into the reaction vessel, add 20mL of DMF (N,N-dimethylformamide ), stirred at room temperature, added 5g of potassium carbonate (36mmol) in batches and reacted for 12h. After the reaction, the reaction solution was poured into ice water to separate out a light yellow solid, which was filtered by suction and rinsed with deionized water. Finally, the filter cake was put into an oven Dry...

Abstract

The invention relates to a preparation method of a [3-2-(N-ethylphenylamino)ethoxyl] zinc phthalocyanine / attapulgite composite photocatalyst. The preparation method comprises the following steps of: pretreatment of attapulgite, preparation of [3-2-(N-ethylphenylamino)ethoxyl] zinc phthalocyanine and preparation of the [3-2-(N-ethylphenylamino)ethoxyl] zinc phthalocyanine / attapulgite composite photocatalyst. The preparation method has the beneficial effects that the composite photocatalyst is low in preparation cost, high in purity and simple in preparation process; effective degradation to a pollutant of malachite green is realized, the photocatalytic activity is obviously better than that of pure [3-2-(N-ethylphenylamino)ethoxyl] zinc phthalocyanine particles, and the composite photocatalyst can be applied to treatment of the pollutants in the environment.

Description

technical field [0001] The present invention specifically relates to the preparation method of [3-2-(N-ethylphenylamino)ethoxy]zinc phthalocyanine / attapulgite composite photocatalyst Background technique [0002] In recent years, metallophthalocyanines have attracted increasing attention in photocatalytic research due to their novel material properties. Phthalocyanine has good catalytic activity, stable chemical properties and good light / heat stability. The central cavity of phthalocyanine contains two hydrogen atoms that can be replaced by other elements, and there are about 70 kinds of replaceable elements. The phthalocyanine compound has an electron conjugated structure of 18π, and the electron density of phthalocyanine is very uniform. The catalytic reaction can take place in the axial position of the plane, and the aromatic ring can act as electron acceptor and electron donor. Due to the special structure, phthalocyanine can decompose large logarithm organic pollutan...
