C+HNO3→CO2↑+NO2↑+H2O中,C元素的化合价由0价升高为+4,升高4,N元素的化合价由+5价降低为+4价,降低1,根据化合价升降相等,因此C的化学计量数为1,NO2的化学计量数为4,HNO3的计量数为4.根据H原子守恒,H2O的化学计量数为2,所以得到C+4HNO3 = ?xml:namespace> CO2↑+4NO2↑+2H2O;NH3+O2→NO+H2O...

The performances of selective catalytic reduction (SCR) of NO/NO2 with NH3 and NO oxidation over MnOx-CeO2/ZSM-5 catalysts were investigated. The result showed that the MnOx dispersions, redox abilities and proportions of Mn4+ of catalysts were enhanced by the doping of CeO2. However, the ...
