摘要: NOx控制是目前大气污染控制领域的重要研究内容，NH3选择性催化还原技术（NH3-SCR）是消除NOx最有效的技术之一，其核心是高性能催化剂的开发。本研究综述了金属负载型分子筛催化剂（Cu基和Fe基分子筛催化剂）的NH3-SCR活性、水热稳定性以及水热老化失活机制，并对影响催化剂水热稳定性的因素（包括Si/Al比、分子筛拓扑结构、活性金属负载量、粒径和合成方法等）进行了系统阐述，总结了一些有效提高催化剂水热稳定性的改性方法，比如磷改性、第二活性金属改性、碱金属改性和外表面改性等。最后，对进一步提高金属负载型分子筛催化剂在NH3-SCR反应中的水热稳定性进行了展望。Abstract: Emission of NOx from stationary and mobile sources had caused many environmental problems. NH3 selective catalytic reduction technology (NH3-SCR) is one of the most effective technologies to eliminate NOx based on developing high-efficient catalysts. In this review, the catalytic activity for NH3-SCR, hydrothermal stability and deactivation mechanism of metal-based zeolite catalysts (mainly Cu- and Fe-based zeolite catalysts) employed in NH3-SCR were summarized. The main factors affecting the hydrothermal stability of Cu- or Fe-based zeolite catalysts in NH3-SCR, such as Si/Al ratio, zeolite topological structure, metal content, particle size and preparation methods of catalysts, were systematically reviewed. The modification approaches addressed in recent researches which could effectively improve the hydrothermal stability of metal-based zeolites in NH3-SCR, such as element modification using phosphorus, second active metal, alkali (earth) metal, and surface modification, were discussed. Hopefully, this review could provide a fundamental understanding of the deactivation behaviors of Cu- and Fe-based zeolite catalysts and pave the way towards the improvement of hydrothermal stability of zeolite catalysts in NH3-SCR.

Figure 1 Estimation of Cu2+, Cu(OH)+ and CuOx in fresh and HTA (high temperature aging) Cu/SSZ-13 samples (Si/Al = 12, Cu loading = 2.1%) with EPR. The HTA samples were hydrothermally aged in flowing air containing 10% water vapor for 16 h at different temperatures (for example, HTA-550 represents treating at 550 ℃), except for HTA-900, which was only aged for 2 h[36] (with permissions from ACS publications)
