The Cover Feature shows the pathways of n ‐alkane isomerization over a Pt/ZSM‐22 catalyst. The n ‐alkane favors to be converted to i ‐alkane over the partially blocked channels, and will be cracked as light alkanes as through the evacuated channels. In this Communication, G. Lv, C. Wang et al. developed a facile in‐situ coke deposition approach to prepare a Pt/ZSM‐22 with partially filled micropore channels. On this catalyst, the conversion of n ‐alkane follows pore‐mouth mechanism, with an improvement of the diffusion of alkene intermediates. This is beneficial for suppression of the cracking reactions, resulting in an enhanced isomers yield, especially multibranched isomers yield in n ‐alkane isomerization reaction. More information can be found in the Communication by G. Lv, C. Wang et al. on page 1431 in Issue 5, 2019 (DOI: 10.1002/cctc.201801695).
