    Adsorbate-driven dynamic active sites in stannosilicate zeolites by Xianfeng Yi, Yao Xiao, Changjiu Xia, Fengqing Liu, Yujia Liu, Yu Hui, Xin Yu, Yucai Qin, Wei Chen, Zhiqiang Liu, Lijuan Song, Anmin Zheng

    Published 2025-01-01
    “…In this study, a dynamic transformation of framework Sn−O−Si sites to Sn−OH/Si−OH pairs and subsequently a pseudo-Brønsted acid in stannosilicate zeolites upon molecular adsorption, which is analogous to various adsorbates/reactants under working conditions, was identified by solid-state nuclear magnetic resonance (NMR) spectroscopy for the first time, which challenges the widespread assumption that the active center structures remain rigid/stable during the catalytic process. …”
