Photocatalytic Concrete

Photocatalysis is an advanced oxidizing process that could be a promising solution to ensure safer indoor environment. Initially photocatalytic processes were developed in direction of applications for water treatment to degrade some specific pollutants or dyes. During the last decade appear new directions as far as concern air depollution because photocatalytic processes were able to oxidize most of common VOCs from indoor air. The use of LiNbO3 photocatalyst in concrete material would be more beneficial since it reduces VOCs from indoor environment and can produce oxygen through artificial photosynthesis. This technology possesses enormous potential for the reduction of “global warming”. This study aims to apply photocatalytic materials to the concrete surface for purifying indoor air and producing artificial photosynthesis. As photocatalyst LiNbO3 may be used as sustainable construction material in near future that will be contribute in VOC’s degradation and in global warming reduction.
