It is highly desirable but challenging to design novel catalyst and achieve efficient and stable CO₂ methanation under mild conditions. Herein, we developed a highly active electron-enriched Y₂O₃/Ni catalyst, achieving a stable operation with ~80.1% CO₂ conversion and ~100% CH₄ selectivity for 400 h at 0.1 MPa and 220 °C, which was a 100 °C lower than the conventional supported Ni-based catalysts. Structural characterizations confirmed that the Y₂O₃/Ni catalyst maintained dynamic redox changes and formed electron-enriched Y₂O_{3–<em>x</em>}-Ni interfaces under reaction conditions. Mechanism studies proved that the Y₂O_{3–<em>x</em>}-Ni interfaces obviously lowered the energy barrier of *HCO dissociation, and shifted the rate-determining step from *HCO dissociation to *CO hydrogenation. Furthermore, profited by the moderate CO_<em>x</em> adsorption ability and higher H₂ coverage at the Y₂O_{3–<em>x</em>}-Ni interfaces, the *CO hydrogenation reaction was kinetically promoted. The above factors accounted for the excellent low-temperature CO₂ methanation activity of the Y₂O₃/Ni catalyst.</div></div>","PeriodicalId":9832,"journal":{"name":"Chinese Journal of Catalysis","volume":"84 ","pages":"Pages 200-213"},"PeriodicalIF":17.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147826528","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}

However, conventional carbon nitride photocatalysts suffer from rapid charge recombination, limited visible-light utilization, and insufficient 2e⁻ ORR selectivity. Herein, we report a novel precursor-molten salt synergistic strategy. Using the oxygen-containing precursor itself, the spontaneous oxygen doping of the carbon nitride skeleton was initiated by a one-step heat-induced condensation process, and the O-doped cyano-functionalized carbon nitride (MCN-N15) was further synthesized by molten salt-assisted synthesis. Under visible light, MCN-N15 achieves an exceptional H₂O₂ production rate of 950.14 μmol·g⁻¹·h⁻¹ in ethanol. O-doping induces n → π* electronic transitions, broadening the visible-light absorption range. Simultaneously, the introduced cyano groups (–C≡N) facilitate charge separation and enhance 2e⁻ ORR selectivity. Crucially, this approach not only realizes the self-doping of O, but also mitigates the conduction band downshifting typically caused by conventional molten salts, yielding a more negative conduction band potential (<em>E</em>_CB = –0.84 V <em>vs</em>. NHE) that provides a strong thermodynamic driving force for 2e⁻ ORR. The results of density functional theory calculations show that the synergistic modification strategy of oxygen doping and cyano modification effectively reduces the Gibbs free energy change (Δ<em>G</em>) of the rate-determining step (* + O₂ → *O₂) and promotes the formation of intermediate *OOH, thereby significantly improving the selectivity and reaction rate of H₂O₂ synthesis. The synergistic modification optimizes the electronic and band structure of carbon nitride, providing a novel “energy band engineering-surface functionalization” co-regulation strategy for designing efficient photocatalytic H₂O₂ generation systems.</div></div>","PeriodicalId":9832,"journal":{"name":"Chinese Journal of Catalysis","volume":"84 ","pages":"Pages 250-260"},"PeriodicalIF":17.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147826634","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}
