Photocatalytic degradation of NOx in a continuous bench-scale reactor using active tiles, experimental data and simulations

In the present work we present a new kind of gas-flow reactor able to test photocatalytic building materials in large size, optimizing the reaction conditions in order to work both with artificial conditions of irradiation (UV-A lamp) and under the direct sunlight. In particular, industrial porcelain grès tiles were tested towards the photodegradation of NOx in air in a continuous experimental setup, either using UV lamps or using the sunlight, studying the effect of different concentration of NOx on the building material performances first, as the effect of different light sources.
