Compared with conventional acidic oxide carriers such as TiO2, it is easier to adsorb acid reaction molecules SO2, which is conducive to the adsorption and activation of reaction molecules, thereby improving the catalytic activity. According to the Tanabe rule, the coordination charge number of ...
However, H2S emission from the Na2S solution under weakly acidic or neutral conditions remained a major problem. Dissolved sulfite ion (S(IV)), such as in Na2SO3/NaHSO3 and (NH4)2SO3/NH4HSO3, can promote NO2 removal [36], [38], [40], [41], [42]. However, according to Littlejohn...
Measurement of atmospheric H2O2was carried out in Los Angeles (the concentration of gaseous H2O2, 0.03–1.35 ppb), the Mojave Desert (0.20–2.04 ppb) and the San Bernardino Mountains (0.43–1.72 ppb) during 1985–88. The H2O2concentrations during midday (1200–1600) can be as high as 1 ppb...
Among the following, the compound that is both paramagnetic and colored is: (a) K2Cr2O7 (b) (NH4)2(TiCl6) (c) VOSO4 (d) K3[Cu(CN4)] The strongest acid amongst the following is: (a) HClO4 (b) HClO3 (c) HClO2 (d) HCl...
Figure 1b describes the XRD patterns of the obtained mixed metal oxides which were derived from the corresponding HTlcs by the calcination process, which mainly contains dehydration, dehydroxylation, and loss of compensating anions, and leads to acidic or basic mixed oxides. No spinel phase was ob...
This is probably related to the formation of sulphate species on the external surface of the catalyst [11,13]. According to the studies carried out by Yu et al. [60], sulphate species improve ammonia adsorption due to their acidic nature. Furthermore, when sulphates react with ammonia on ...
