Abstract
Methods for embedding photocatalytic titanium dioxide in concrete surfaces to reduce pollutants via photocatalytic reactions are provided herein. One method includes mixing a solvent compound with an anatase titanium dioxide (TiO2) photocatalyst, applying an amount of concrete treatment compound to an upper surface of the concrete, the concrete treatment compound comprising a mixture of a liquid carrier compound with the anatase titanium dioxide (TiO2) photocatalyst.
