Herein, we have constructed a series of N-doped porous carbon confined Co nanoparticles (CoNC) based on the pyrolysis of Co-containing ZIF-67 at different temperatures for the synthesis of FAM from FUR. The reductive amination activity of as-obtained CoNC catalysts shows a volcano plot as the pyrolysis temperature increases. The optimal CoNC-750, obtained by pyrolysis at 750 ℃, could afford a maximum FAM yield up to 99 % at 110 ℃, 0.3 MPa of NH₃, 2 MPa of H₂ in methanol, reflecting one of the excellent performances in terms of FAM yields for Co-based catalysts. Besides, no apparent deactivation of the CoNC-750 is observed after six consecutive runs, indicating an excellent stability. Through a combination of advanced characterizations, a positive linear relationship between the densities of the strong acid sites and the corresponding FAM productivities of CoNC catalysts has been revealed, indicating that the strong acid density is a key descriptor for facilitating the FUR-to-FAM transformation. This study provides an efficient approach for fabricating high-performing non-noble metal catalysts for the reductive amination of biomass-derived platform molecules, which could be of great aid for green and sustainable production of primary amines and beyond.</div></div>","PeriodicalId":264,"journal":{"name":"Catalysis Today","volume":"466 ","pages":"Article 115672"},"PeriodicalIF":5.3,"publicationDate":"2026-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145882180","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}

Ball milling for 2 h activated hydroxyl defects on iron slag, enabling metastable Ca₂Fe₂O₅ formation at a CaO/Fe₂O₃ molar ratio of 1:1.5, which enhanced toluene diffusion and activation.

Pore morphologies were retained after this ABC-type ALD/calcination/additional Al₂O₃ ALD, confirming the thin film deposition occurs without compromising pore structure of the Al₂O₃ support. Calcination after 15 cycles of ABC-type ALD is required to recover the DRM activity as well as to improve the stability.
