ABSTRACT The fine‐tuning of the electronic structure and local environment surrounding atomically dispersed metal centers is crucial in catalysis but remains a grand challenge that requires in‐depth exploration. In this study, Ir species were incorporated into series UiO‐type metal−organic frameworks via strong metal–support interactions (SMSI), their state was precisely modulated by regulating metal‐oxo clusters (Ce, Zr, Hf) organic ligands (BDC‐X, where X = ‐H, ‐NH 2 , ‐Me, or ‐NO ) for enhancing catalytic performance dicyclopentadiene (DCPD) hydrogenation. optimized Ir@Ce‐UiO‐66‐NO effectively transforms DCPD tetrahydrodicyclopentadiene (THDCPD), giving 100% conversion over 99% THDCPD selectivity, far superior to corresponding counterparts. Experimental theoretical results jointly demonstrated Ce‐oxo with unique Ce III /Ce IV redox pairs can facilitate electron transfer species. Furthermore, electron‐withdrawing groups play role increasing ratio, promoting efficient uptake MOF support leading low density around species, which enhances stronger between substrate molecules active sites contributes excellent activity. findings presented work provide valuable insights rational design advanced heterogeneous catalysts leveraging properties modulation capabilities supports.

Chemical recycling of plastic waste, especially polyolefins, into valuable liquid fuels is considerable significance to address the serious issues raised by their threat on environmental and human health. Nevertheless, construction efficient economically viable catalytic systems remains a significant hurdle. Herein, we developed an bifunctional catalyst system comprising γ-Al2O3-supported ruthenium nanoparticles (Ru/γ-Al2O3) β-zeolite for conversion polyolefins gasoline-range hydrocarbons. A yield C5–12 paraffins up 73.4% can be obtained with polyethene as reactant at 250 °C in hydrogen. The Ru sites primarily activate initial cleavage C–H bonds polymer towards formation olefin intermediates, which subsequently go through further cracking isomerization over acid β-zeolite. Employing situ infrared spectroscopy probe–molecule model reactions, our investigation reveals that optimized proportion spatial distribution dual are pivotal tandem process. This optimization synergistically regulates kinetics accelerates intermediate transfer, thereby minimizing production side C1–4 hydrocarbons resulting from over-cracking enhancing fuels. research contributes novel insights design chemical upgrading chemicals, advancing field waste sustainable production.
