Hexamethyleneimine (HMI) serves as a pivotal intermediate in the pharmaceutical, agrochemical, and insecticide industries. Industrial HMI production is currently constrained by limited scale and stringent process requirements. This study presents a novel strategy for the selective synthesis of HMI through vapor-phase one-step amination of 1,6-hexanediol (HDO) with ammonia, catalyzed by cost-effective NiO-decorated Cu/TiO₂. Under 1.5 MPa and 215 °C, the NiO-Cu/TiO₂ catalyst achieves complete HDO conversion, with a 98.5 % HMI selectivity and a 1.4-fold enhancement over copper active site alone. Comprehensive characterizations, including XRD, TEM, SEM-EDS, and XPS, elucidate the electronic interactions between copper and nickel oxide that nickel oxide incorporation effectively mitigates charge accumulation on copper, enhancing its hydrogenation capacity and facilitating the conversion of enamine intermediates to imines. DFT calculations reveal that dehydrogenation and hydrogenation processes are rate-determining steps of alcohol amination reaction. This catalyst system, leveraging inexpensive transition metals, holds promise for industrial-scale HMI production via efficient HDO amination.</div></div>","PeriodicalId":243,"journal":{"name":"Applied Catalysis A: General","volume":"709 ","pages":"Article 120615"},"PeriodicalIF":4.8,"publicationDate":"2025-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219068","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Their catalytic performances in ammonia decomposition were investigated under conditions of 5 % NH₃ at 1 bar, within a temperature range of 300 °C to 600 °C, and a weight hourly space velocity of 15.000 ml_N g_cat⁻¹ h⁻¹.

They unraveled that non-pyrolyzed supports showed a strong tendency for Ru agglomeration, whereas pyrolyzed supports exhibited improved metal distribution, which correlated with enhanced catalytic activity exceeding 50 % ammonia conversion at 450 °C. The surface chemistry of the carbon support was modified by varying the pyrolysis temperature, which affected the concentrations and types of oxygen and nitrogen surface groups. These changes altered the interaction between Ru and these surface groups. During the decomposition of the Ru precursor and the reduction of Ru oxides, the partial breakdown of oxygen and nitrogen surface groups led to surface reconstructions of the Ru nanoparticles, thereby affecting their crystallinity. This phenomenon was also observed during the catalytic testing, which was more pronounced on the HC-600 support. Modifying the surface chemistry of hydrochar via pyrolysis affects Ru distribution, reducibility, and crystallinity, thereby enhancing the NH₃ decomposition performance.</div></div>","PeriodicalId":243,"journal":{"name":"Applied Catalysis A: General","volume":"709 ","pages":"Article 120616"},"PeriodicalIF":4.8,"publicationDate":"2025-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219082","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Different loadings of manganese were deposited on the catalysts using incipient wetness impregnation before the impregnation of cobalt and rhenium. All the Mn-promoted catalysts exhibited an increase in chain growth probability and olefin content in the products. This enhanced C₅₊ selectivity is attributed mainly to decreased methane production. The promotion of the catalytic activity was dependent on the support material. On γ−Al₂O₃ the catalyst activity increased with increasing manganese loading. Using a narrow pore silica support (SiO₂−N) a maximum in the activity was found at an intermediate manganese loading. Further addition of Mn decreased the activity and worsened the product distribution with an increase in methane selectivity. The catalysts supported on TiO₂ and wide pore silica (SiO₂−W), did not show major activity changes with Mn addition. The addition of Mn decreased the metallic surface area in most cases, indicating blocking of Co sites. The pore structure and the metal−support interactions play a role in how the Mn and Co are dispersed, yielding enhanced or inhibited activity. The origin of the promotion was investigated with CO and syngas adsorption experiments coupled with recording DRIFTS spectra. The results indicated a decrease in CO bond energy due to an increase in electron density of the Co with the Mn addition. The electronic effect appeared to be in balance with the site blocking of Mn.
