Structure and Acidity Changes in Ultra-Stable Y Zeolites During Hydrothermal Aging: A Solid-State NMR Spectroscopy Study

Structure and Acidity Changes in Ultra-Stable Y Zeolites During Hydrothermal Aging: A Solid-State NMR Spectroscopy Study

Structure and acidity changes of the acid sites in ultra-stable Y zeolites of different cell sizes during the hydrothermal aging process were studied by solid-state nuclear magnetic resonance (NMR) combined with molecular probes. The experimental results demonstrated that, during the initial stage o...
