Greatly improved zeolite membranes were prepared by using high‐aspect‐ratio zeolite seeds. In their Communication on page 10843 ff. , S. Li, M. Yu, et al. report about slice‐shaped seeds with a large aspect ratio that facilitate growth of thinner SAPO‐34 membranes with much higher quality. These membranes show high performance in separating N 2 /CH 4 mixtures. Fine tuning the crystal structure by changing the crystal composition might be a feasible way for further improving the separating performance.
