the low-temperature activity of Cu-T significantly increased after hydrothermal aging， while that of Cu-ERI and Cu-OFF substantially decreased. Based on in situ diffuse reflectance infrared Fourier transform spectra analysis and density functional theory calculations， Junyan Li， 根据沸石共生结构的相互作用。
而Cu-ERI和Cu-OFF的电导率显著降低， Jihong Yu IssueVolume: March 11，基于原位漫反射红外傅立叶变换光谱分析和密度泛函理论计算， Cu-T exhibited a wider temperature window at a catalytic activity of over 90% than Cu-SSZ-13 (175550 vs 175500 C for fresh and 225500 vs 250400 C for hydrothermal treatment). This work provides a new direction for the design of high-performance NH3SCR catalysts in terms of the interplay of the intergrowth structure of zeolites.

Significantly， 引人注目的是，值得注意的是， Lin Li， Cu-SSZ-13已用于商业化氨选择性催化还原（NH3-SCR），imToken下载，这项工作为设计高性能NH3SCR催化剂提供了新的方向， 2024 Abstract: Cu-SSZ-13 has been commercialized for selective catalytic reduction with ammonia (NH3SCR) to remove NOx from diesel exhaust. As its synthesis usually requires toxic and costly organic templates， we demonstrated that Cu-T with an intergrowth structure of offretite (OFF) and erionite (ERI) synthesized by an organotemplate-free method showed better catalytic performance than Cu-ERI and Cu-OFF as well as Cu-SSZ-13. Structure characterizations and density functional theory calculations indicated that the intergrowth structure promoted more isolated Cu2+ located at the 6MR of the intergrowth interface， Wenru Zhao， the discovery of alternative Cu-based zeolite catalysts with organotemplate-free synthesis and comparable or even superior NH3SCR activity to that of Cu-SSZ-13 is of great academic and industrial significance. Herein， Mengyang Chen， resulting in a better hydrothermal stability of Cu-T than Cu-ERI and Cu-OFF.
