Nitrogen-doped carbon (NC) materials have become the most promising carbon-based electrocatalysts to produce CO and potential metal carriers to produce multi-carbon products due to their low cost, high activity, and ability to enhance metal–carrier interactions. However, aiming at high selectivity of CO, it is important to optimize the competing coverage of *CO and *H on the NC working electrocatalyst surface. Here, for the first time, we controllably adjusted the pyrrolic-N content on NC <em>via</em> a simple strategy of pyrrolic-N-abundant phthalocyanine-assisted pyrolysis of a common MOF precursor (ZIF-8), which then modulated the *CO and *H coverage for enhanced electrocatalytic CO₂ reduction to CO with an FE_CO value of above 92% at −0.6 V <em>vs.</em> RHE. Mechanistic studies showed that the high content of pyrrolic-N of Pr-a-NC induced the surface coverage of *CO to be much higher than that of the control samples. Meanwhile, under the conditions of high *CO coverage, adsorbed *CO intermediates combined with the active *H generated the high-coverage intermediate *COH, which is one of the most common intermediates to generate multi-carbon products. So, this work not only provides an effective strategy for the future rational design of carbon electrocatalysts to generate CO, but also opens an avenue to engineer carbon–nitrogen coordination substrate-loaded metal electrocatalysts for the production of multi-carbon products from the eCO₂RR.</div></div>","PeriodicalId":66,"journal":{"name":"Catalysis Science & Technology","volume":"15 9","pages":"Pages 2898-2907"},"PeriodicalIF":4.4,"publicationDate":"2025-03-17","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143911879","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Complete conversion of FFA was achieved within 1 h at 170 °C and 4 MPa H₂, with a 54% selectivity to 1,5-PeD. The production rate reached 13 mol_1,5-PeD mol_Co⁻¹ h⁻¹, the highest value reported so far. The kinetic studies revealed that the reaction rate had a first order dependence on both hydrogen pressure and FFA concentration, with an apparent activation energy of 76 kJ mol⁻¹. Characterization using H₂-TPR, H₂-TPD, and XPS revealed that compared with 5Co/MgO and 5Co/ZrO₂, the 5Co/CeO₂ catalyst had the highest Co⁰/Co²⁺ ratio (0.69) and abundant oxygen vacancies. Moreover, the oxygen vacancy concentration increased with the reduction temperature of 5Co/CeO₂, and linearly correlated with the reaction rate. Raman, FFA-DRIFTS, and substrate control experiments showed that FFA was adsorbed on oxygen vacancies with both the furan oxygen and hydroxyl oxygen atoms. This unique adsorption mode facilitated the ring opening reactions. Co⁰ was responsible for hydrogen activation while the oxygen vacancies from both the interfacial Co²⁺ and CeO₂ were responsible for FFA adsorption. The good synergy between the Co⁰ and the adjacent oxygen vacancies allows the efficient conversion of FFA to 1,5-PeD.

The hydrogenation of butyramide to butylamine as a model reaction was used to evaluate the catalytic performance. The catalytic activity of the Ru catalyst supported on rutile TiO₂ was superior to that on anatase TiO₂. As the calcination temperature increased from 200 °C to 600 °C, the catalytic performance of Ru/rutile catalysts monotonously decreased. With the reduction temperature increasing from 200 °C to 600 °C, Ru/rutile catalysts displayed a volcano-like trend of catalytic activity.
