Problems solved by technology

However, since the growth of LDHs is not easy to be controlled when electrochemically preparing LDHs, currently only Ni / Al-LDHs are prepared by electrochemical methods (CN103811199A; J.Gong, Biosensors and Bioelectronics, 2009, 25, 493-496; H.Liang, Electrochemistry Communications ,2012,20,149-152) and Zn / Al-LDHs (A.Mignani, et al.Journal Physical Chemistry C,2013,117,16221-16230) research reports
The reported methods for preparing NiZn / Al-LDHs are: thermal decomposition method (H.Yi, et al.Catalysis Communications, 2011,12,1492-1495) and co-precipitation method (H.Chen, et al.International Journal of Hydrogen Energy, 2002, 27, 489-496), there is no relevant research report on the preparation of NiZn / Al-LDHs composite materials by electrochemical method
In addition, because LDHs materials are layered compounds with a scale of micron, it is difficult to recycle and separate them in practical applications.

Abstract

The invention discloses a preparation method of a nickel-zinc-aluminum / carbon fiber composite material, which comprises the following steps: by using CFs (carbon fibers) as a working electrode, immersing the CFs in a mixed solution A, and generating a polyaniline-doped quercetin precursor film on the CFs by cyclic voltammetry, which is recorded as CFs / AH; by using the CFs / AH as a working electrode, immersing in a mixed solution B, regulating the pH value of the system to 2-6 with a pH regulator, depositing NiZn / Al-LDHs at normal temperature in a nitrogen atmosphere by cyclic voltammetry, crystallizing at 40-100 DEG C for 3-13 hours, cooling to room temperature, washing with distilled water, and carrying out vacuum drying to obtain the CFs-NiZn / Al-LDHs composite material. The CFs-NiZn / Al-LDHs composite material prepared by the method has favorable photoelectric catalytic performance and adsorbability, is convenient to operate and easy to separate, and can be directly used as a working electrode to perform photoelectric catalytic reaction.
