Promotion of catalyst nanoparticles, electrochemical promotion (NEMCA) of porous and of single-crystal catalyst films, and metal nanoparticle-support interactions are three, at a first glance, independent phenomena that can all dramatically affect catalytic activity and selectivity on metal and metal oxide catalyst surfaces. 

In this study, we report our results aimed investigating the potential promotion of catalyst activity/lifetime by inclusion of a low level of CO in the feed. Attention has been directed towards a study of the nature of the coke species formed both in the presence and absence of CO, over ZSM-5 (Si/Al= 47) based catalysts which have been deliberately prepared so as to contain the a-MoCi-x phase.
