Abstract

The invention discloses a preparation method and application of a copper selenide nano material based on an eggshell template, and belongs to the technical field of nano materials. The composite copper selenide nano material is prepared by using discarded eggshells as the template, loading copper ions on the surfaces of the eggshells and combining selenium ions in situ to form copper selenide nanoparticles. The preparation method comprises the following steps of eggshell pretreatment; preparation of carrier eggshells; copper ion adsorption; reduction of sodium selenite; in-situ combination ofthe copper ions with the selenium ions to form the copper selenide nanoparticles; preparation of the composite copper selenide nano material loaded on the eggshells. The composite copper selenide nanomaterial has high catalytic degradation performance for organic dyes. The preparation process is simple and easy, a material source is rich, and the catalytic effect is excellent.

Description

technical field [0001] The invention belongs to the technical field of nanomaterials, and in particular relates to a copper selenide nanomaterial based on an eggshell template, a preparation method and an application thereof. Background technique [0002] As we all know, water is a very precious natural resource and an essential substance for human life. With the rapid development of world industry and the continuous increase of population, the human demand for water is increasing day by day. China is a country short of water resources. my country's per capita water resources (fresh water) only account for 1 / 5 of the world's, ranking 88th in the world. At the same time, human beings' already limited water resources are increasingly polluted. In 1999, the total discharge of domestic industrial and urban domestic wastewater was 40.1 billion tons. At present, China's industrial wastewater discharge volume is large and the pollution concentration is high. There are many reason...
