Revealing the CO<sub>2</sub> adsorption blocking mechanism in flexible low-silica small-pore zeolites <i>via</i> three-dimensional electron diffraction
Low-silica small-pore zeolites are essential for CO<sub>2</sub> selective adsorption; however, some Na-form flexible types exhibit negligible performance. Advanced three-dimensional electron diffraction elucidated the blocking mechanism: Na<sup>+</sup> ions in elliptical 8-rings hinder CO<sub>2</sub> diffusion. Structural insights guided the design of K-form types with wider 8-rings, achieving enhanced CO<sub>2</sub> adsorption.
