Abstract

The inside back cover picture displays the effects of different Zr promoters (framework Zr or ZrO2) on catalytic performance of PtSn/MCM‐41 catalysts for the ethane dehydrogenation to ethene. Moderate interaction between Si‐O‐Zr and PtSn promotes formation and stabilization of highly active and selective Pt3Sn/Pt species, which contributes to the enhancement of initial reactivity, coke tolerance and stability. More details are given in the article by Zou et al. on page 918—924.image
