“…4B). According to literature [17], NH 3 may be significantly produced from NO reduction under this reductive condition, and hence the S N2 calculated by the Eq. (3) under this condition should be considered as the sum of selectivity of NO reduced to N 2 and NH 3 .…”

“…In the past decades, various hydrocarbons [8][9][10][11][12][13][14] have been studied as reductant for the purpose of removing NO x in excess oxygen, which was expressed as HC-SCR, whereas their poor activity and selectivity under low temperature towards the aimed reaction make this technology hardly developed. Recently, hydrogen [15][16][17][18][19][20][21][22] has been proved to be effective reductant for NO x reduction in excess oxygen because of its high activity towards NO reduction and zero emissions of greenhouse gases in the reaction. Recent research works [5][6][7] have revealed that this reaction under industrial conditions is possible and the SCR of NO by H 2 (H 2 -SCR) might be a breakthrough NO x control technology in favor of the NH 3 -SCR in application.…”

“…H-ZSM-5 is also regarded to perform as a catalyst to selectively produce N 2 from NH 3 and NOx [6], both of which are intermediate products of DMF. In contrast, the reactants and byproducts hardly adsorbed on basic ZrO 2 [7,8], and thus would be easily released outside of the reaction system. SiO 2 displayed a medium activity between that of H-ZSM-5 and ZrO 2 , probably due to not having either strong acidity or basicity [9].…”
