Fe-N<sub><em>x</em></sub> and graphitic N sites were quantified by X-ray photoelectron spectroscopy (XPS) to determine their ratios. The interaction between Fe-N<sub><em>x</em></sub> and graphitic N and the mechanism affecting the catalytic activity were systematically explored by combining experiments and theoretical calculations. The results indicated a significant synergistic effect between Fe-N<sub><em>x</em></sub> and graphitic N. Especially, Fe-N-C with a 1:4 ratio of Fe-N<sub><em>x</em></sub> to graphitic N owned the highest turnover frequency (TOF) value (1.59 × 10<sup>−3</sup> g m<sup>−2</sup> min<sup>−1</sup>). The contributions of radical mechanism influenced TOF values of Fe-N-C-rx to a certain extent. Theoretical calculations proved that the coordination environment could regulate the electronic structure of active sites, thereby affecting catalytic activity. Fe-N-C with a ratio of 1:4 Fe-N<sub><em>x</em></sub> to graphitic N had maximum adsorption energy (<em>E</em><sub>ads</sub>), O-O bond length (<em>l</em><sub>O-O</sub>) and the optimal d-band center value, which promoted adsorption and electron transfer with PS.

Herein, we exploited a new hydrophobic metal-organic framework (MOF) by a post-synthesis acid-exchange method. Pentadecafluorooctanoic acid (PFOA) was applied to substitute the acetic acid of MOF-808 to result in the fluorinated MOF-808-PFOA, which owns much larger water contact angle than the primary MOF-808. Further, we successfully loaded these sub-micron MOF-808-PFOA particles into a melamine (MA) sponge, <em>via</em> the crosslinking effect by polydimethylsiloxane (PDMS). The prepared MOF/PDMS/MA sponge shows a high contact angle of 151.9°, induced by the increased surface roughness of mesh filament and decreased surface energy. Meanwhile, it is found that this excellent hydrophobility remains well under different water media and pH values. Combining with the high hydrophobiclity, mechanical stability and porous structure, this sponge shows an excellent adsorption performance for various classes of organic oils, with the large saturated adsorption capacities (27–65 g g<sup>−1</sup>), short equilibrium time (∼3 s), and good recyclability. More interestingly, this sponge can serve as a filter cartridge to achieve the effective continuous oil-water separation, even under long-term use. Thus, our work provides a new sponge-based adsorbent for efficient oil-water separation, and proposes a feasible strategy to construct hydrophobic MOFs <em>via</em> post-synthesis methods.</div></div>","PeriodicalId":100481,"journal":{"name":"Environmental Functional Materials","volume":"3 1","pages":"Pages 25-33"},"PeriodicalIF":0.0,"publicationDate":"2024-03-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142586853","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
