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

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 Brønsted acid sites and reducing the pore size of the zeolite.
