Photocatalytic Activity for NO Degradation by Construction Materials: Parametric Study and Multivariable Correlations

Degradation of pollen on nanofunctionalized photocatalytic materials

“…In the last decade, photocatalysis has been postulated as a promising solution to help in reducing contamination of the air especially in urban agglomerations due to its ability to mineralise airborne contaminants such as NO x , volatile organic compounds, etc . Also it is widely used for material functionalization yielding anti‐bacterial, anti‐fungal and self‐cleaning properties .…”

A Novel Method for the Combined Photocatalytic Activity Determination and Bandgap Estimation

“…Assuming that a generic photocatalyst, having a band gap of E 0 , is activated by an electromagnetic radiation having a wavelength at λ<hcE0, it will exhibit photocatalytic activity A NO , only when radiated by LEDs 2, 3, 4, 5 and 6. Moreover, the relation between photon flow (light irradiance) and photocatalytic activity, for Ee < 1 Wm −2 , expressed as NO oxidation rate, can be considered linearly dependent [16,17].…”

“…A few authors have already implemented LEDs as a luminous source to activate the photocatalysts, in order to study of the photocatalytic activity of such materials towards the degradation of gaseous pollutants [6,7,9,10], water pollutants [8,11,12,13], dyes [14] and bacteria inactivation [15,16]. As the choice of a suitable light source is a fundamental choice, the use of an array of LEDs, characterized by different emitted wavelengths, can provide more information on the photocatalysts under examination.…”

From analysis to decision: Revision of a multifactorial model for the in situ assessment of NOx abatement effectiveness of photocatalytic pavements

“…at the road pavement. During the last decade extensive studies have been undertaken to assess the performance of various types of photocatalytic pavement materials using laboratory scale experimental and simulation approaches [1,2,8,11,13,16,18,[20][21][22]27,28]. Some studies scaled up and tested in full-scale pilot projects which were focused on evaluation of the performance of photocatalytic pavements on urban streets under real world conditions [1,[3][4][5]7,9,14,15,24,25,30,32,33].…”
