  Abstract

Biomass-derived 2,5-dimethylfuran was employed as a renewable feedstock to investigate the structure-performance relationship of zirconium- and chromium-based metal-organic frameworks (MOFs) for the production of p-xylene. Three frameworks, UiO-66(Zr), MOF-808(Zr), and MIL-101(Cr), were synthesized to evaluate how pore structures affect reactivity and selectivity, and to confirm that framework openness governs diffusion and intermediate stability. The sulfonic acid functionalization of UiO-66(Zr) and MIL-101(Cr) promoted dehydration and aromatization and enhanced the catalytic performance by strengthening the Brønsted acidity. Notably, the sulfonated MOFs exhibited strong Lewis-Brønsted synergy, resulting in a significantly improved p-xylene yield. This study shows that pore and acidity modulation are viable strategies for MOF catalyst design.
