Traditional zeolite-catalyzed cracking of polyolefins to produce aromatics often needs high temperatures and faces issues like low selectivity for liquid aromatics, separation difficulties, and rapid catalyst deactivation due to coking. To address this, a multifunctional Ni/HZSM-5 catalyst was developed to efficiently upgrade various polyolefins—including polyvinyl chloride—into gaseous alkanes (C<sub>1</sub>–C<sub>5</sub>) and easily separable liquid aromatics (C<sub>6</sub>–C<sub>12</sub>) at 400 °C, without added solvents or hydrogen. Aromatic products make up 57.1 wt% of total output, with more than 97.8 % selectivity for the liquid phase and a BTX (benzene, toluene, and xylene) selectivity of 76.1 %. The high activity and selectivity for aromatics stem from synergistic interactions between Ni nanoparticles (NPs) and acid sites in the zeolite, which promote selective C–C bond breaking and control hydrogenolysis and aromatization pathways. This synergy allows precise control over the distribution of products by carbon number and favors the formation of separable aromatics. Notably, the catalyst also prevents coking by hydrogenolyzing and hydrogenating reactive intermediates before they form stable graphite-like deposits. Consequently, Ni/ZSM-5 catalyst demonstrates excellent stability, maintaining consistent aromatics yield over 13 consecutive cycles and processing over 30 times its weight in plastics without regeneration. After regeneration, the activity of the catalyst was fully restored, highlighting its potential for industrial use.

NiCo-based catalysts have emerged as promising candidates for glucose oxidation reaction owing to the intrinsic activity of Ni and Co catalytic centers. However, the dynamic evolution and atomic-scale synergy between these centers remain elusive. Herein, we fabricated NiCo<sub>2</sub>O<sub>4</sub> nanosheets supported on nickel foam, where Ni preferentially occupies tetrahedral sites to regulate the electronic configuration of octahedral Co. Experimental and theoretical results demonstrate that the incorporation of tetrahedral Ni induces low-to-intermediate spin transition in octahedral Co, thereby optimizing <em>e</em><sub>g</sub> orbital occupancy and stabilizing active sites. This spin-state engineering establishes Ni-Co synergistic catalytic centers for the selective oxidation of glucose to formate (FA). At higher potential (≥1.4 V vs. RHE), octahedral Co undergoes reconstruction into excessive active CoOOH and CoO<sub>2</sub> species, resulting in glucose overoxidation to CO<sub>2</sub> and intensified competitive oxygen evolution. In contrast, at lower potentials (<1.4 V vs. RHE), tetrahedral Ni facilitates electron delocalization across the Ni–O–Co lattice, thereby stabilizing octahedral Co for glucose adsorption and oxidation. Subsequently, a coupled electrocatalytic system was constructed, achieving 80.7 % FA yield with 91.3 % Faradaic efficiency (FE) at NiCo<sub>2</sub>O<sub>4</sub> anode and H<sub>2</sub> evolution rate of 696 μmol h<sup>−1</sup> with 99.9 % FE at Pt cathode for 2 h under 1.35 V vs. RHE. This work provides a deep insight into spin-state regulation of the catalytic center, offering valuable guidance for rational catalyst design.</div></div>","PeriodicalId":15728,"journal":{"name":"Journal of Energy Chemistry","volume":"112 ","pages":"Pages 605-617"},"PeriodicalIF":14.9,"publicationDate":"2025-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145156432","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
