摘要 采用两步水热法在三聚氰胺海绵碳泡沫基底(MF)上原位合成MnCo纳米阵列脱硝催化剂用于NH3选择性催化还原NOx,并研究了Co改性对Mn-MF低温性能的影响。结果表明:Co改性可以显著提高Mn-MF的低温活性、N2选择性以及抗水抗硫性能;Mn2Co-MF催化剂具有相对最优的低温活性,在140~220 ℃温度区间内,其脱硝效率可达90%以上。此外,通过SEM、XRD、XPS和H2-TPR、NH3-TPD等不同表征手段探讨了Mn2Co-MF催化剂的催化性能、氧化还原性能和结构之间的关系;Co的引入不仅可以增大催化剂的比表面积和孔容,而且还可以促进Mn2Co-MF催化剂表面氧物种的富集,能够产生更多的酸性位点,提高催化剂的还原性,从而提高其活性。

Abstract: Atwo-step hydrothermal method was applied to synthesize the MnCo nanoarray denitration catalyst on carbon foam substrate (MF) for the selective catalytic reduction of NOx by NH3. The effect of Co-doping on the low temperature performance of Mn-MF was also studied. The results show that Co-doping can significantly improve the low-temperature activity and selectivity of Mn-MF and the resistance of H2O and SO2. The Mn2Co-MF catalyst has the best low-temperature performance and the denitration efficiency can reach more than 90% at 140—220 ℃. In addition, SEM, XRD, XPS, H2-TPR, NH3-TPD and other characterization techniques are applied to explore the relationship between the catalytic performance, redox performance and structure of Mn2Co-MF catalyst. The results show that the introduction of Co can not only increase the specific surface area and pore volume of the catalyst, but also promote the enrichment of oxygen species on the surface of the Mn2Co-MF catalyst, produce more acid sites, and improve the reducibility of the catalyst, thereby improving the low temperature activity.
