As for the removal of NO the

As for the removal of NO, the oxidation of NO was the key, which could be demonstrated from the experiments of in the absence and presence of the oxidants, as shown in Table 2. H2O2, PAA, and radicals such as HO· and HO2· participated in the oxidation of NO, in which, the primary oxidant, H2O2, played a leading role in the NO oxidation (Eq. (15)), and other oxidants further enhanced the oxidation (Eqs. (16), (17) and (18)). The NOx KY02111 also occurred in the process (Eqs. (19), one gene one polypeptide hypothesis (20) and (21)) [20], [21], [22], [23], [24], [25], [26], [27], [28], [29], [30], [31], [32], [33], [34], [35], [36], [37], [38], [39], [40], [41], [42] and [43].equation(15)2NO+3H2O2→2NO3−+2H++2H2Oequation(16)NO+2HO•→NO2+H2ONO+2HO•→NO2+H2Oequation(17)NO2+HO•→NO3−+H+equation(18)HO2•+NO→NO3−+H+equation(19)NO2+NO+H2O→2NO2−+2H+equation(20)2NO2+H2O→NO3−+2H++NO2−equation(21)3NO2+H2O→2NO3−+2H++NO
