摘要：

The Cu/SAPO-34 zeolite serves as an efficient active component for the selective catalytic reduction (SCR) of nitrogen oxides (NOx) in flue gas by ammonia. Despite its commendable high-temperature hydrothermal stability, the application of Cu/SAPO-34 zeolite is limited due to low-temperature hydrothermal deactivation issues in the steam environment. In this paper, we provide a systematic review on the denitration mechanism, low-temperature hydrothermal deactivation mechanism, factors influencing its low-temperature hydrothermal stability, and the corresponding improvement measures of Cu/SAPO-34 zeolite. Additionally, the advantages and disadvantages of different methods are analyzed to offer valuable insights for future research.
