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 H<sub>2</sub>O<sub>2</sub> production rate of 950.14 μmol·g<sup>−1</sup>·h<sup>−1</sup> in ethanol.

Hydrodesulfurization causes aromatic saturation, impairing the suitability of slurry oil as needle coke feedstock. Therefore, developing methods capable of selective desulfurization while preserving aromatics is essential. Herein, we address the critical challenges impeding the application of oxidative desulfurization (ODS) to slurry oil, specifically its complex composition, high sulfur content, prohibitively high viscosity, and inefficient oil-water interfacial mass transfer. An innovative ODS strategy based on biphasic interface regulation was proposed. By constructing a catalytic system through the combination of polyoxometalate and organic cationic modifiers to stabilize the oil-water interface, enhanced mass transfer efficiency was achieved. These catalysts function as surfactant-like homogeneous catalysts during H<sub>2</sub>O<sub>2</sub> mediated oxidation, while enabling rapid separation after reaction. Systematic model system studies identified catalysts with exceptional sulfur-oxidation selectivity, operating <em>via</em> dynamic peroxo-species formation from terminal oxygen of W=O activation by superoxide radicals. Deployment in real slurry oil under Bayesian-optimized conditions reduced sulfur content from 1.60 wt% to 0.34 wt% while completely preserving the core feedstock components 3–4 ring aromatic components and maintaining 86.4% slurry recovery. This research provides a technologically innovative and practically viable pathway for desulfurization of slurry oils with remaining high aromatic contents.</div></div>","PeriodicalId":9832,"journal":{"name":"Chinese Journal of Catalysis","volume":"84 ","pages":"Pages 375-389"},"PeriodicalIF":17.7,"publicationDate":"2026-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"147826694","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}
