THE USE OF NANO-SIZED NATURAL SILICA TO VISIBLE LIGHT PHOTOCATALYST AS A MASK COATING FOR INACTIVATION OF SARS-CoV-2:A REVIEW

摘要

Research on antiviral agents to inactivate SARS-CoV-2 is still a concern of researchers.Many innovations have been made,one of which is coating the surface of cloth masks using photocatalyst materials.Visible light photocatalysts have been shown to have antimicrobial properties in sunlight.The study of material modification becomes important to select and optimize the supporting materials used.We observed that modifications with nano-silica particles(SiC2)have good transmission capabilities and can be produced from natural sources(biological and non-biological).Therefore,this utilization is carried out to apply the principle of zero waste,namely renewable natural sources as a source/precursor of nano-silica.In this study,we focus on renewable research related to the use of natural nano-silica as supporting material for visible light photocatalysts will be explored to be coated on polyester mask fabrics as an effort to inactivate SARS-CoV-2 on the surface of the mask.
