Selective catalytic reduction of NO<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub> with NH<jats:sub>3<\/jats:sub> (NH<jats:sub>3<\/jats:sub>-SCR) is proved to be one of the most efficient techniques for reducing NO<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub> emission. Recently, Cu-SSZ-13 catalyst has been recognized as a promising candidate for NH<jats:sub>3<\/jats:sub>-SCR catalyst for reducing diesel engine NO<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub> emissions due to its wide active temperature window and excellent hydrothermal stability. Despite being commercialized as an advanced selective catalytic reduction catalyst, Cu-SSZ-13 catalyst still confronts the challenges of low-temperature activity and hydrothermal aging to meet the increasing demands on catalytic performance and lifetime. Therefore, numerous studies have been dedicated to the improvement of NH<jats:sub>3<\/jats:sub>-SCR performance for Cu-SSZ-13 catalyst. In this review, the recent progress in NH<jats:sub>3<\/jats:sub>-SCR performance optimization of Cu-SSZ-13 catalysts is summarized following three aspects: 1) modifying the Cu active sites; 2) introducing the heteroatoms or metal oxides; 3) regulating the morphology. Meanwhile, future perspectives and opportunities of Cu-SSZ-13 catalysts in reducing diesel engine NO<jats:sub><jats:italic>x<\/jats:italic><\/jats:sub> emissions are discussed.<\/jats:p>","DOI":"10.3389\/fchem.2022.1033255","type":"journal-article","created":{"date-parts":[[2022,10,17]],"date-time":"2022-10-17T06:59:34Z","timestamp":1665989974000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":18,"title":["Recent progress in performance optimization of Cu-SSZ-13 catalyst for selective catalytic reduction of NOx"],"prefix":"10.3389","volume":"10","author":[{"given":"Pan","family":"Li","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ying","family":"Xin","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hanxue","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Fuzhen","family":"Yang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ahui","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Dongxu","family":"Han","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Junxiu","family":"Jia","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jin","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhenguo","family":"Li","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Zhaoliang","family":"Zhang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2022,10,17]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"120054","DOI":"10.1016\/j.apcatb.2021.120054","article-title":"Recent advances in hybrid metal oxide-zeolite catalysts for low-temperature selective catalytic reduction of NOx by ammonia","volume":"291","author":"Andana","year":"2021","journal-title":"Appl.
