This document summarizes a project that studied the potential for a new porcelain ceramic tile called BIONICTILE® impregnated with a photoactive ingredient called OFFNOX® to reduce nitrogen oxide levels in the atmosphere. The project was conducted using the EUPHORE atmospheric simulation chambers, which are well equipped to simulate urban air pollution conditions. Results showed that the BIONICTILE® tiles were able to reduce nitric acid levels and uptake over 130 mg of NOx per square meter, representing a potential new way to help reduce air pollution in cities.
