Abstract: The synthesis of valuable aromatics via CO 2 transformation, especially para -xylene (PX), is of paramount significance but still remains greatly challenging due to the low efficiency and poor selectivity. The present work utilized a composite catalyst based on ZnZrO x with a modified H-ZSM-5 exhibiting nano-prism stacking to realize the selective synthesis of PX. Methoxy species generated from CO 2 -derived formate produced as an intermediate over the ZnZrO x were readily incorporated into the xylene products for effective alkylation, contributed to an enhanced aromatics-based cycle that provided a selectivity for xylenes among all C 5+ hydrocarbons of 91.1 %. The lengthened straight channels in the H-ZSM-5 along the b -axis, derived from the crystal stacking pattern, increased differences in the diffusion properties of the xylene isomers, and thereby steering the movement of molecules toward a product shape-selective pathway, leading to 90.1 % selectivity for PX among all xylenes, and provided exceptional CO 2 utilization efficiency of ∼60 %. [Display omitted] • 90 % xylene containing 90 % PX was produced in aromatics over ZnZrO x &C-Z5. • Tandem reaction mechanism contributes the high yield of xylene. • Stacking structure oriented along specific axis regulates the anisotropic product diffusion. • Lengthened diffusion path in straight channel reinforce selective synthesis of PX.
