Keywords: green products; nanomaterials; NO oxidation; photocatalysis; SnO2; Review Introduction A World Health Organization (WHO) report indicated that 4.2 million deaths every year occur due to exposure to ambient (outdoor) air pollution [1]. This number is much higher than the deaths from

• photoinduced electrons from the CB of BiOBr to that of SnO2, thus prolonging the lifetime of photogenerated electron–hole pairs (Figure 8). The NO-to-NO2 conversion and intermediates and products were confirmed via in situ diffuse reflectance infrared Fourier transform spectroscopy during NO oxidation [70

• . This is a clear indication that the final product is free from impurities and no oxidation of silver has occurred. The crystallite size was calculated using the Scherrer equation. The crystal size was found to be 27 nm, which is smaller than the diameter of the silver nanowires calculated from the SEM

• %. This degree of oxidation is lower than in the case of chemically exfoliated MoS2, which is possibly due to a slightly lower degree of exfoliation [39]. Additionally, no oxidation was observed for sulfur as only states originating from sulfides were identified in the S 2p spectrum (Figure 3b) [40]. The

There is no oxidation of Ag nanocrystals in contrast to the general statement that Ag nanoparticles are very reactive

To allow for a detailed comparative study of the magnetic characteristics of the samples the absolute amount of deposited Fe is the same for all samples, namely a 6 nm equivalent film thickness of clusters, and the Fe cluster concentration was
