Abstract

The invention relates to the technical field of formaldehyde removing materials, and discloses a formaldehyde removing materialof graphene nano composite gel. The formaldehyde removing material is prepared from the following components in parts by weight: 8-9 parts of crystalline flake graphite, 6-8 parts of hydrogen peroxide, 3-4 parts of sodium nitrate, 10-14 parts of concentrated sulfuric acid, 5-7 parts of hydrogen chloride and 25-28 parts of potassium permanganate. According to the formaldehyde removing material of the graphene nano composite gel and the preparation process, water molecules and oxygen in the air can be excited by efficiently utilizing light energy of visible light, so that free formaldehyde and other organic pollutants in the air are thoroughly decomposed into water and carbon dioxide harmless to the human body, and the effect of efficiently decomposing formaldehyde is achieved.

Description

Technical field [0001] The present invention relates to the technical field of formaldehyde materials, and in particular a graphene nanocomposite gel, a formaldehyde material and a preparation process. Background technique [0002] In order to adapt to the requirements of the air quality, various types of air purifiers have occurred, most of which use porous materials such as activated carbon to adsorb harmful gases in the air, but the adsorption capacity of activated carbon by the adsorption material is limited, and the adsorption is saturated In the future, there will be a pollutant penetration. There is also an organic substance such as formaldehyde in the air, or a negative ion generator is used to improve the air quality, and the ordinary photocatalyst only reaches the effect of decomposing formaldehyde under ultraviolet light, but the ultraviolet region in the sun is smaller. The content is relatively low. Therefore, although ordinary light ties have functions that have lon...
