摘要 含氨废气的排放对人类健康和生态环境有十分严重的影响。采用选择性催化氧化(SCO)技术实现含氨废气污染控制具有良好的应用前景,铜基催化剂因其优良的催化性能而受到广泛的关注。本文总结分析了近期国内外对于铜基催化剂应用于NH3-SCO体系的研究成果与进展,指出了不同活性组分、载体以及其他因素对催化剂性能的影响;简要阐述了NH3-SCO的反应机理,重点讨论了以铜为主要活性位的催化剂机理研究;并对未来的研究工作进行了展望,指出采用多种手段对催化剂进行改性、进一步研究催化剂在实际体系中的应用以及采用原位等谱学手段对催化机理进行深入探讨是该领域的研究重点。 Exhaust emissions containing ammonia(NH3) have very serious influence on human health and the environment. Ammonia selective catalytic oxidation(NH3-SCO) has a good application prospect in pollution control of waste gas containing NH3. Copper-based catalysts have been widely studied because of their excellent catalytic performance. This paper summarized and analyzed the recent progress of copper-based catalysts in NH3-SCO. The effects of active component,support and other factors on the performance of the catalysts were discussed respectively. The mechanism of NH3-SCO was briefly described,with the emphasis on the catalyst with copper as the main active site. Modifying the catalyst by different methods,studying the practical application of catalyst and using in situ spectroscopic techniques to further probe the mechanism will be the hotspots in the field.
