“…Interaction is here ascribable to physisorption in accordance with experimental results, 48 at ambient temperatures likely favouring desorption. We therefore discarded MoO 3 from further discussion.…”

Present experiments show that synthesized polycrystalline hexagonal α-Mo 2 C is a highly efficient and selective catalyst for CO 2 uptake and conversion to CO through the reverse water gas shift reaction. The CO 2 conversion is ~16% at 673 K, with selectivity towards CO > 99%. CO 2 and CO adsorption is monitored by DRIFTS, TPD, and show that polycrystalline α-Mo 2 C is an economically viable, highly efficient, and selective catalyst for CO generation using CO 2 as a feedstock.

“…CO adsorbs only on the reduced Mo species after activation. [85,86] With FTIR distinct vibrations for different Mo sites present in the zeolite can be observed after activation of those sites has been completed. [87,88] Using this technique combined with theory, information about the oxidation state as well as nuclearity of the reduced Mo can be gained for this system.…”

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

et al. 2018

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.

“…It was found that Mo 2 C in combination with ZSM-5 zeolite effectively catalyzes the aromatization of CH 4 with 80% selectivity at about 10-15% conversion [31][32][33][34]. Since this reaction has been observed neither on pure Mo 2 C nor ZSM-5 alone, it was thought that the role of Mo 2 C is the activation of CH 4 to yield CH 3 and CH 2 radicals with a certain lifetime on Mo 2 C to couple into C 2 H 4 [35]. The formed C 2 H 4 can be oligomerized and aromatized on the acidic sites of ZSM-5.…”
