Highly selective conversion of CO2 to para-xylene over tandem catalysts

ZnZrO/Mg-Si-ZSM-5 tandem catalysts enable CO2 hydrogenation to para-xylene (PX) with PX selectivity up to 28% and a proportion of PX in xylene up to 84%. SiO2 and MgO modification increases the PX selectivity by reducing the Bronsted acid sites and reducing the pore size of the zeolite.

Automated summary

ZnZrO/Mg-Si-ZSM-5 tandem catalysts modified with SiO2 and MgO increase the selectivity of para-xylene (PX) in CO2 hydrogenation by reducing Bronsted acid sites and pore size of the zeolite, leading to PX selectivity up to 28% and a proportion of PX in xylene up to 84%.
