Using a combination of experiments and first-principle calculations, we found that pyrrolic N, characterized by a higher adsorption energy, increases the charge storage capacity of the electrode at high frequencies.

Highly graphitized porous carbon, denoted GC-800, was synthesized by polymerization at room temperature followed by carbonization at 800 °C using phenolic resin as the precursor and FeCl₃ as the iron source. Vienna Ab-initio Simulation Package (VASP) calculations confirmed a higher binding energy between C₂H₆ molecules and graphitized porous carbon surfaces, so that a high degree of graphitization increased the adsorption capacity of porous carbon for C₂H₆. However, catalytic graphitization using Fe at high temperatures disrupted the microporous structure of the carbon, thereby reducing its ability to separate C₂H₆/C₂H₄. By controlling the carbonization temperature, the degree of graphitization and pore structure of the porous carbon could be changed. Raman spectra and XPS spectra showed that the GC-800 had a high degree of graphitization, with a sp² C content as high as 73%. Low-temperature N₂ physical adsorption measurements estimated the specific surface area of GC-800 to be as high as 574 m²·g⁻¹. At 298 K and 1 bar, it had an equilibrium adsorption capacity of 2.16 mmol·g⁻¹ for C₂H₆, with the C₂H₆/C₂H₄ (1:1 and 1:9, <em>v</em>/<em>v</em>) ideal adsorbed solution theory selectivity respectively reaching 2.4 and 3.8, significantly higher than the values of most reported high-performance C₂H₆ selective adsorbents. Dynamic breakthrough experiments showed that GC-800 could produce high-purity C₂H₄ in a single step from a mixture of C₂H₆ and C₂H₄. Dynamic cycling tests confirmed its good cyclic stability, and that it could efficiently separate C₂H₆/C₂H₄ even under humid conditions.</div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"39 5","pages":"Pages 1027-1036"},"PeriodicalIF":5.7,"publicationDate":"2024-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142533730","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"材料科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Using heavy oils containing distinct chemical groups as the carbon source, namely fluid catalytic cracking slurry (FCCS), petroleum asphalt (PA) and deoiled asphalt (DOA), three carbon nanosheets (CNS) were prepared through a molten salt method, and used as the anodes for PIBs. The composition of the heavy oil determines the lamellar thicknesses, sp³-C/sp²-C ratio and defect concentration, thereby affecting the potassium storage performance. The high content of aromatic hydrocarbons and moderate amount of heavy component moieties in FCCS produce carbon nanosheets (CNS-FCCS) that have a smaller layer thickness, larger interlayer spacing (0.372 nm), and increased number of folds than in CNS derived from the other three precursors.
