Breaking down harmful gases and killing bacteria and viruses


Whitewash: Powerful Photocatalyst for Air and Water Purification and Disinfection

“Whitewash” is a proprietary coating with titania composite nanofiber photocatalyst with graphene. The coating allows light, harmful gas molecules, bacteria and viruses to pass through to be in contact with the nanofibres. Upon light harvest, photogenerated electrons and holes that react with oxygen and water vapor in air produce large amounts of radicals. By oxidation, the radicals convert harmful gases to harmless substances and kill bacteria/viruses.
