Abstract: Catalytic diesel, characterized by high aromaticity (>60 wt%), is a challenging yet promising feedstock for producing high‐value benzene, toluene, and xylene (BTX). High‐efficiency hydrocracking requires a synergistic metal‐acid balance between hydrogenation‐dehydrogenation and acid‐catalyzed cracking. However, the mechanism by which different Ni introduction routes and loadings modulate the structure and catalytic properties of Y zeolite remains insufficiently understood. This study addresses this gap by systematically investigating the impact of varying Ni contents and three distinct introduction methods‐impregnation, ion‐exchange, and in situ synthesis‐on the physicochemical properties of Y zeolites and the resulting NiWS catalysts. Characterization results reveal that the introduction method is pivotal in tailoring the metal‐acid synergy. Among the series, impregnation‐modified catalysts with an optimal 2 wt% Ni loading maximized accessible acidity and active‐phase dispersion, enhancing hydrocracking selectivity. Conversely, the ion‐exchange approach yielded the highest WS2 slab stacking and superior W dispersion, delivering a peak BTX yield of 55.96%. While in situ synthesis incorporation significantly improved mesoporosity to facilitate reactant diffusion, the ion‐exchange strategy proved most effective for balancing metal‐support interactions. These findings provide novel and fundamental insights into the rational design of bifunctional catalysts for aromatic‐rich diesel valorization. [ABSTRACT FROM AUTHOR]
