This cover by Yingfei Zheng, Yonghong Wu, Bing Zhang and Zhi Wang shows the SEM image of the morphology of mixed matrix membranes (MMMs) made from Pebax and NaY zeolite. The incorporation of NaY is favorable for improving the affinity towards CO 2 , the free fractional volume, and the structural modification of MMMs. As the result, the as‐obtained MMMs present significantly increased CO 2 permeability and CO 2 /N 2 selectivity in comparison to the neat Pebax membranes. The separation data of MMMs surpass the 2008 Robeson's upper bound for CO 2 /N 2 . DOI: 10.1002/app.48398
