Abstract

The invention discloses an rGO / Mg (OH) 2 photocatalytic reactor with activated carbon fiber cloth as carrier. The preparation method comprises the following steps: (1) preparing GO: preparing by an improved Hummers method; (2) preparation of rGO / Mg (OH) 2 composites: preparing GO / Mg (OH) 2 composites by chemical precipitation method using GO and MgCl<2>.6 H2O as raw materials, reducing GO with green reductant, and dispersing Mg (OH) 2 nanoparticles uniformly on rGO nanoparticles by adjusting the content of GO and reaction time, so as to obtain rGO / Mg (OH) 2 composites; (3) preparation of activated carbon fiber cloth: using viscose polyester and cotton blended fabric to prepare that activated carbon fiber cloth through opening, carding, airflow netting, carbonization and activation technology, and then pretreating the surface of the activated carbon fiber cloth; (4) preparation of rGO / Mg (OH) 2 photocatalytic reactor with the above cloth as carrier: using impregnation-drawing method toload the GO / Mg (OH) 2 composites on the surface of the carrier to prepare the photocatalytic reactor. At that same time, the invention realizes high-value use of the waste resource, endows the photocatalytic characteristic of the material, realizes the immobilization of the photocatalytic material in power form, and has good application prospect in the field of environmental treatment.

Description

technical field [0001] The invention belongs to the technical field of photocatalytic materials, in particular to a preparation method for growing ZnO nanorod arrays on the surface of activated carbon fiber cloth. Background technique [0002] The problem of environmental pollution has attracted more and more people's attention and attention, and the decolorization and purification treatment of polluted wastewater has become very important. Photocatalytic technology uses solar energy as energy, and has the advantages of simple operation, mild reaction conditions, and no secondary pollution. At present, the most widely used photocatalytic materials are titanium dioxide, zinc oxide and their composites, which are difficult to recycle. Graphene oxide is a new type of inorganic material with special structure and superior performance. Due to its single atomic layer composition, it has certain limitations, which leads to inevitable agglomeration and greatly limits the applicatio...
