NOx degradation in a continuous large-scale reactor using full-size industrial photocatalytic tiles

Many reactors were proposed to investigate the efficiency of photocatalytic materials in the degradation of NOx, but the operative conditions are often very far from reality: the parameters and the reactor set-up, which are good for laboratory tests, cannot verify the real efficiency of a photocatalytic material in a real context. To solve this issue, we experimented for the first time with a new kind of gas-flow reactor able to test photocatalytic building materials of large size, optimizing the reaction conditions in order to work both under artificial conditions of irradiation (UV-A lamp) and under direct sunshine.
