Issue 8/2020 - The solid catalytic materials developed by Dahua Institute can be used to adsorb and inactivate the new coronavirus

Recently, the Dalian Institute of Chemicals of the Chinese Academy of Sciences has developed a catalytic material
that can adsorb and inactivate the new coronavirus.

The results of the virus inactivation experiment conducted by the Anhui Provincial Center for Disease Control and Prevention show that the material has the effect of directly adsorbing and inactivating the new coronavirus, and the inactivation efficiency is 96.
5%~99.
9%.

In this experimental environment, the concentration of the new coronavirus was 5 micrograms/ml, which was much higher than the virus pathogenic concentration
in real life scenarios.
Such solid catalytic materials are non-toxic, insoluble in water and organic solvents, can be made into particles or carried on various carriers, and are expected to be used in anti-epidemic products and daily air and water purification products to achieve adsorption and inactivation of viruses and improve the level
of protection.

From a chemical point of view, the biological macromolecules such as proteins, ribonucleic acids, and fat membranes contained in viruses are not as stable as ordinary organic small molecules, and are easy to hydrolyze or oxidize and inactivate
.
Therefore, based on the adsorption performance, acidity and alkalinity, redox and other chemical properties of solid materials, it is theoretically feasible
to achieve the adsorption and inactivation of viruses.
