摘要：

It is crucial to control NOx emissions into the atmosphere for the environment and health. Many technologies are available for NOx removal, selective catalytic reduction(SCR)is one of the most effective technologies for NOx removal. The reduction of NO by CO offers a simple and low-cost technology for flue gas denitrification (CO-SCR), and direct decomposition of NO is regarded as the most ideal and environmentally friendly technology for the removal of NOx. As an efficient catalyst for NOx removal, Cu ion zeolite catalysts have wide temperature windows and good hydrothermal stability. In this review, the research progress of Cu ion zeolite catalysts in NOx removal is studied. The NH3-SCR, CO-SCR, and direct catalyst decomposition of NO on the Cu ion zeolite catalysts are discussed, involving the reaction mechanism of Cu ions zeolite catalysts as well as the effect Cu active sites. In addition, the poison-resistant properties of Cu ion zeolite catalysts to H2O and SO2 are also summarized. And the future development of Cu ion zeolite has been discussed. © 2024 Cailiao Daobaoshe/ Materials Review. All rights reserved.
