Embodiment

[0033] An in-situ self-assembly preparation method of a zinc tetrasulfophthalocyanine / zinc oxide composite membrane nanomaterial, the specific steps of which are:

[0034] (1) The ITO conductive glass was ultrasonically washed with cleaning agent, acetone, ethanol and deionized water respectively, with an interval of 10 minutes each time, and then dried in an oven at 80°C for later use;

[0035] (2) Put the washed ITO into 200 mL containing Zn(CH) with a concentration of 20 mM. 3 COO) 2 and hexamethylenetetramine (HMTA); the beaker was placed in a 90°C water bath for 1 h, then the ITO was taken out, washed gently with deionized water, dried naturally, and finally placed in a muffle furnace for 300 calcined for 30 min at ℃, the heating rate was 5 ℃ / min, and finally the dumbbell-shaped ZnO nanofilm material attached to the ITO conductive glass was obtained;

[0036] (3) Dissolve 0.0416 g of sulfophthalonitrile in 40 mL of N,N-dimethylformamide (DMF), and ultrasonically dissolv...

Abstract

The invention discloses an in-situ self-assembly preparation method of a tetrasulfonated zinc phthalocyanine / zinc oxide compound membrane nano-material. The method comprises the following steps: (1) synthesizing a dumbbell-shaped ZnO nano-membrane material on ITO conductive glass; (2) dissolving sulpho-phthalic nitrile in a DMF solvent; (3) immersing the dumbbell-shaped ZnO nano-membrane material adhered to the ITO conductive glass in the sulpho-phthalic nitrile solvent; and (4) putting the immersed ITO conductive glass in a tube furnace, calcining to prepare the nano-material. In the preparing process, the tetrasulfonated zinc phthalocyanine (ZnTSPc) is formed on the ZnO surface in an in-situ self-assembly mode, and the organic matter and inorganic matter compound material has clean interface, chemical bonding and good stability, so that the visible light absorption spectrum of the compound material can be widened, the separation efficiency of photogenerated charge can be improved, and the photocatalytic degradation efficiency can be greatly improved. The tetrasulfonated zinc phthalocyanine / zinc oxide compound membrane nano-material is hydrophilic, and has the selective photocatalytic degradability for hydrophilic organic dye.
