“…Such a decrease of the reaction rate with increasing concentration of water in the gas phase was in fact reported by several authors. 45,52,53,56,60,63 The rate law presented in eqn (19) was used to analyse kinetic data recently published by Hunger et al 60 (see ESI, † Part III). A good agreement between experimental and calculated data is observed (ESI, † Fig.…”

“…However the reduction was not maximized, caused by the degradation process's being carried out in a closed reactor, thereby limiting the amount of oxygen involved. Martinez et al (2011) conducted previous research on reactive species of oxygen deficiency due to the fact that sufficient moisture in the air inhibits NO photocatalytic degradation at high pollutant concentrations. Figure 7 shows that the CN-TiO 2 -450/PS catalyst has lower photocatalytic activity than does CN-TiO 2 -350/PS in the degradation of MCH, even when it is compared to P25/PS.…”

“…In recent years, many studies in the literature have been devoted to understand and improve the degradation of NO x by photocatalysis using TiO 2 -containing materials (TiO 2 is used as an additive and mixed with cement and concrete) or TiO 2 -based dispersions (TiO 2 is used as a coating such as glaze and paint). Focus has especially been made on the NO x photocatalytic oxidation mechanism [15,18], the factors affecting the photocatalysis process [19][20][21][22], the experimental setup at a laboratory scale [23][24][25][26][27][28], and the development of photocatalysts active under visible light and the photocatalysis efficiency at real scale [29][30][31][32][33][34][35].…”

“…However, the reported photocatalytic degradation efficiency may vary from one study to another depending on the experimental conditions and the scale of the experiment. The air purification ability of TiO 2 is commonly studied at laboratory scale using flow-type reactors with different geometries and modes of operation simulating various environmental parameters [15,16,20,23,36]. A consensus between researchers was established, and a standardized experimental apparatus was defined to allow the performance of photocatalytic samples to be compared and also to identify the important parameters coming into play [5,25,26].…”
