Progress in Developing a Structure‐Activity Relationship for the Direct Aromatization of Methane

To secure future supply of aromatics, methane is a commercially interesting alternative feedstock. Direct conversion of methane into aromatics combines the challenge of activating one of the strongest C−H bonds in all hydrocarbons with the selective aromatization over zeolites. To address these challenges, smart catalyst and process design are a must. And for that, understanding the most important factors leading to successful methane C−H bond activation and selective aromatization is needed. In this review, we summarize mechanistic insight that has been gained so far not only for this reaction, but also for other similar processes involving aromatization reactions over zeolites. With that, we highlight what can be learnt from similar processes. In addition, we provide an overview of characterization tools and strategies, which are useful to gain structural information about this particular metal‐zeolite system at reaction conditions. Here we also aim to inspire future characterization work, by giving an outlook on characterization strategies that have not yet been applied for the methane dehydroaromatization catalyst, but are promising for this system. Direct Aromatization of Methane: This article is an up‐to‐date look on research regarding the structure‐activity‐relationship of the zeolite based catalyst for the methane dehydroaromatization (MDA) reaction. Recent findings from MDA research are summarized and compared to spectroscopic studies and discoveries for similar catalytic systems. The review aims to both give a better understanding of the structure‐activity relationship for the MDA catalyst and to inspire further studies on this topic.
