A solution against air pollution and COVID-19?

The University of Cambridge together with the industry group HeidelbergCement are interested in the properties of the graphene material and more precisely to its "filter capacities". Combined with the titanium dioxide and under the action of sunlight, it can be used as a coating on buildings and clean the air. It can also be used as a composite with fabric for sewn mouth and nose protection masks, which are efficient for 48 hours and even longer! In addition, it can be used as a virucide in certain conditions. Will self-stitched masks soon become obsolete?
