Suitable Bifunctional Catalyst to Produce DME by CO2 Hydrogenation

Bifunctional Cu-based-HZSM5 catalytic systems were investigated to shed lights into the key functionalities that control their catalytic behavior in CO₂ hydrogenation reaction. The results obtained demonstrate that the distribution of the active sites (metal-acid) and the reactor configuration play a fundamental role in order to obtain high yields in CH₃OH/DME.
