Photocatalytic Concrete : New Era in Sustainable Construction

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.
