Catalyst deactivation causes major losses in the chemical industry worldwide every year. The deactivation phenomenon does not only drop the catalytic activity, but forces an allocation of time and a regeneration of resources, which, at the same time, involves wasting more feedstock and materials, and emitting more CO2. Catalyst deactivation can occur by means of metal sintering, phase transformation, thermal degradation, and coke deposition. Regeneration per-se is a costly process and is detrimental for the carbon balance that can potentially, and irreversibly, harm the valued catalysts. The limitless chase of better catalysts with enhanced properties elevates the trouble even more, as both deactivation and regeneration are more challenging.
