For many people who renovate their new houses, the most worrying thing is whether the formaldehyde content in the newly installed furniture at home exceeds the standard. No matter whether the formaldehyde content in the air exceeds the standard or not, we will habitually take some measures to remove formaldehyde. There are many ways, and some people may want to know whether graphene has the effect of removing formaldehyde?

Can graphene remove formaldehyde? According to relevant tests, formaldehyde begins to volatilize when the ambient temperature reaches 19 degrees Celsius, and the volatilization of formaldehyde increases by 40% for every 1 degree increase in ambient temperature. In every cubic meter of air, if the formaldehyde concentration exceeds 0.06mg, it will cause mild asthma in children; if it exceeds 0.1mg, it will feel peculiar smell; if it exceeds 0.5mg, it will irritate the eyes and even tear; if it exceeds 0.6mg, it will cause throat discomfort or pain. ; More than 1mg, it will cause nausea, vomiting, cough, chest tightness, wheezing, and even edema; if more than 30mg, it will cause immediate death. At present, the products that remove formaldehyde on the market include carbon packs, air purifiers, etc., but the adsorption effect on formaldehyde is relatively limited.

Since graphene was developed in 2004, it has been gradually applied to many fields of production and life by virtue of its good physical and chemical properties such as high specific surface area, electrical conductivity, thermal conductivity, and high strength, and the use of graphene to remove formaldehyde is a Brand new graphene industrial application results.

Can graphene effectively remove formaldehyde? Perhaps many people are skeptical. In fact, any conclusion needs to be verified by a large number of experiments.

Graphene has strong adsorption properties for specific gases, giving activated carbon a larger specific surface area, which can greatly improve the adsorption effect of activated carbon. In addition, graphene improves the activity of related catalysts to decompose organic matter, so that harmful substances can be removed safely and efficiently. For the same quality of graphene and adsorption carbon, the saturated absorption of formaldehyde by graphene is 115 times that of adsorption carbon.

Graphene removal of formaldehyde may be used as a key to open the door to a new antibacterial and formaldehyde removal, which will be better used in life or in some household products.
