Abstract

The invention discloses a room temperature formaldehyde-removing material based on a copper catalyst. The room temperature formaldehyde-removing material comprises the following raw materials: modified crystalline flake graphite, activated carbon, a copper nitrate solution, palygorskite and montmorillonite. The invention further discloses a preparation method of the room temperature formaldehyde-removing material based on the copper catalyst. The room temperature formaldehyde-removing material based on the copper catalyst prepared in the invention has an excellent formaldehyde-removing effect.According to mutual match of the modified crystalline flake graphite, palygorskite and montmorillonite, the synergetic effect is achieved, and the formaldehyde-removing effect can be effectively improved. The non-noble metal series copper serves as the catalyst, so that the cost is effectively reduced, the modified crystalline flake graphite, activated carbon, palygorskite and montmorillonite with high adsorption rate and high specific surface area are taken as raw materials, the cost is low, the formaldehyde-removing efficiency is high, and the material has wide market prospects.

Description

technical field [0001] The invention relates to the field of environmental protection treatment, in particular to a material for removing formaldehyde at room temperature based on a copper-based catalyst and a preparation method thereof. Background technique [0002] With the continuous development of society, people pay more and more attention to the environment. Among them, indoor air quality is more concerned by people because it is closely related to people's lives. Indoor air pollution has a serious threat to human life and health. Among them, formaldehyde, as a major pollutant, is a colorless gas with a strong pungent smell. It has strong carcinogenic and cancer-promoting effects. For the health of human body, it is necessary to adopt appropriate methods to remove formaldehyde. The catalyst system can also achieve formaldehyde decomposition at a certain temperature, but the reaction temperature is too high. [0003] At present, catalytic oxidation, as a commonly use...
