Preparation method for growing ZnO nanorod array on surface of activated carbon fiber cloth

Abstract

The invention discloses a preparation method for growing ZnO nanorod array on a surface of activated carbon fiber cloth, and belongs to the technical field of photocatalytic materials. The method comprises the following steps: (1), preparation of two-dimensional activated carbon fiber cloth: preparing the two-dimensional activated carbon fiber cloth through viscose polymeric fiber fabric and the most mature preparation technology for preparing activated carbon fiber cloth through waste organic fiber; (2), pretreating and drying the fiber cloth, and then leaving the fiber cloth to be standby; (3), preparing a zinc oxide crystal seed solution; (4), growing a ZnO crystal seed layer on the surface of the activated carbon fiber cloth; (5), preparing a ZnO nanorod growth solution; (6), growing ZnO nanorods on the surface of the activated carbon fiber clot. The method ensures that hybrid polymer fiber fabric realizes high-value utilization, meanwhile gives a novel photocatalysis function to materials, and has an important application prospect in the fields of photocatalysis environment governance and batteries.

Description

Technical field [0001] The invention belongs to the technical field of photocatalytic materials, and particularly relates to a method for preparing a ZnO nanorod array grown on the surface of an activated carbon fiber cloth. Background technique [0002] With the increasingly serious environmental pollution, the problem of environmental pollution has attracted more and more attention and attention. The decolorization and purification of polluted wastewater becomes crucial. Photocatalytic technology uses solar energy as energy source and has the advantages of simple operation, mild reaction conditions, and no secondary pollution. At present, the most widely used photocatalytic material is titanium dioxide and its composites, while TiO 2 It is not easy to recycle and has a high cost. ZnO has a similar band gap, which is cheaper and non-toxic. In recent years, the use of semiconductor materials as photocatalysts to treat organic pollutants in water has developed rapidly. ZnO, as ...

Problems solved by technology

However, nano-ZnO materials are most commonly used in the photocatalytic treatment of wastewater in powder form. It is difficult to recycle after use, and it is easy to cause secondary pollution and affect its practical application effect. In order to overcome the above problems, it is necessary to find a suitable support. Immobilizing catalysts with substances becomes the key to technology
