- 摘要：
- It is found that formamide species as a crucial intermediate of the selective catalytic reduction of NO by C2H2 Was produced by nitrate species reacting with acetylene in Eley-Rideal mode on H-ferrierite (HFER) based catalyst. The mode concerning the formamide intermediate formation was proposed for the first time in selective catalytic reduction of NO by hydrocarbons. Impregnation of 2% zirconium into HFER considerably favored the formation of formamide species, and therefore better catalytic activity for the title reaction was obtained on 2%Zr/HFER.
