Description

technical field [0001] The invention belongs to the technical field of nanomaterials, and in particular relates to a metal oxide composite nanomaterial based on an eggshell membrane template, a preparation method and an application thereof. technical background [0002] With the development of industrialization and urbanization, more and more pollutants (such as: organic dyes, heavy metals, etc.) people's quality of life. At present, dyes have become one of the important chemical products essential to industry. According to statistics, more than 100,000 types of dyes (about 7×10 5 tons), of which at least 1 / 4 is discharged into the water, causing great pollution. Some dyes can cause skin allergies and mutagenesis, leading to the appearance of cancer. There are many treatment methods for dye wastewater. Traditionally, they mainly include electrochemistry, membrane filtration, ozonation, and adsorption. These methods have the disadvantages of high cost, complicated operati...
