Here, we developed a Ni-Fe/CeO₂/CNT catalyst and unveil the effect of Fe for steam reforming of toluene (SRT) which is a representative tar model compound. The catalyst demonstrated exceptional stability (above 80 % toluene conversion, 3000 mmol/g_cat/h H₂ yield) over 50 h. The outstanding performance is attributed to the effect of Fe in forming Ni-Fe alloy with the highest reducibility, dispersion, Ni⁰ ratio, and increased sintering resistance, alongside enhanced electron transfer between Ni and Fe. Fe also promotes H₂O adsorption, providing active oxygen for toluene conversion and carbon elimination. Finally, reaction mechanism was explored based on the <em>in-situ</em> DRIFTS and DFT calculations. DFT calculations revealed that Fe sites exhibit higher density of states, electrostatic potential, and <em>d</em>-band center than Ni sites, facilitating H₂O coordination. Fe doping reduces energy barriers for H₂O splitting and methyl dehydrogenation, while Ni promotes H₂ desorption. The synergistic Ni-Fe interaction enables distinct activation of toluene and H₂O, respectively. Comparative studies showed Ni/CeO₂/CNT suffers from carbon deposition, while Fe/CeO₂/CNT exhibits limited activity due to poor reducibility and low Fe⁰ content. These findings provide critical insights for designing stable Fe-based catalysts for efficient tar removal.</div></div>","PeriodicalId":243,"journal":{"name":"Applied Catalysis A: General","volume":"705 ","pages":"Article 120424"},"PeriodicalIF":4.7,"publicationDate":"2025-07-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144570424","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}

Herein, iron-doped molybdenum carbide is designed and fabricated for the first time as an efficient OER catalyst due to improved reactant adsorption.

Herein, a one-pot strategy is used to fabricate a novel porous carbon-metal oxide catalyst by pyrolyzing a Co-SiO₂@Co-MOF-74 composite precursor and etching the SiO₂ template. Notably, tunable carbon channels with encapsulated cobalt clusters are formed in situ, and a defined strong electronic interaction between them is demonstrated. Owing to the strong interfacial interaction in this unique microreactor, cobalt oxide clusters can be anchored in a highly dispersed state to provide hierarchical carbon pores and promote charge transfer from the carbon channel to the metal sites. This process leads to enhanced reactant adsorption and activation, thereby promoting the catalytic activity of C-H bond oxidation in toluene. Under optimized conditions, Co-MSC-2 afforded 28 % conversion of toluene and 96 % selectivity for benzaldehyde, and the catalyst maintained remarkable stability.
