A low-pressure SiCl₄ treatment (LPST) strategy to selectively relocate zeolite framework aluminum atoms into the desired positions is reported in the Research Article by Zhengxi Yu, Zhongmin Liu et al. (DOI: 10.1002/anie.202116990). After treatment, the undesired framework aluminum atoms in the 12-MR channels of a mordenite zeolite migrate to the desired T₃ sites to increase the number of favorable active sites.
