Investigation on Parameters Affecting the Effectiveness of Photocatalytic Functional Coatings to Degrade NO: TiO<sub>2</sub> Amount on Surface, Illumination, and Substrate Roughness

<div>Surface appearance of substrates tested: mortar W/C = 0.4 (a), mortar W/C = 0.5 (b), and painted wood (c). Surface roughness mean values: 130 <i>μ</i>m, 11 <i>μ</i>m, and 15 <i>μ</i>m for mortar W/C = 0.4, mortar W/C = 0.5, and wood (see Section <a href="https://static.hindawi.com/articles/ijp/volume-2017/6241615/figures/#sec3.2">3.2</a>).</div>
