Abstract

The invention discloses a mesoporous cuprous oxide and copper oxide composite nanomaterial capable of efficiently adsorbing methyl blue, as well as controllable synthesis and application thereof. The preparation of the composite nanomaterial comprises the following steps: dispersing copper oxide into deionized water, and carrying out ultrasonic concussion to obtain a reaction liquid; using pulse laser to irradiate the reaction liquid; taking a solution after the irradiation is finished, and carrying out centrifugation and ultrasonic treatment so as to obtain the mesoporous cuprous oxide and copper oxide composite nanomaterial. The composite nanomaterial prepared in the invention is high in adsorption rate for methyl blue and high in efficiency, a relatively high adsorption quantity can be reached within short time by using a relatively small using amount, the preparation method is simple, effective, low in cost, green and environment-friendly, and the synthesis of the nanomaterial is greatly simplified.

Description

technical field [0001] The invention relates to a mesoporous cuprous oxide and copper oxide composite nanomaterial capable of efficiently adsorbing methylene blue and its controllable synthesis and application, belonging to the field of preparation and application of new nanomaterials. Background technique [0002] Clean fresh water resources are an indispensable basic condition for the survival of biological species in nature, and it is also a vital prerequisite for a healthy life for human beings. However, with the rapid development of fine chemicals such as printing and dyeing, papermaking, medicine, textiles, and electroplating, a large amount of organic pollutants are discharged, causing serious damage to the current limited fresh water resources. In particular, organic pollutants containing complex benzene rings and aromatic heterocyclic compounds have stable chemical properties and are not easily degraded by light, heat, and oxidants. Discharge into nature will pollut...
