Seedlings of <em>V. faba</em> planted in this peat soil were treated with either distilled water (CK) or 25 mg·L⁻¹ (G25) of functionalized graphene solution. Results showed that the height and root length of <em>V. faba</em> seedlings in the G25 group were significantly larger than those in CK group. The microbial community was analyzed by amplifying and sequencing the 16S rRNA gene V3–V4 region of bacteria and internal transcribed spacer region of fungi in rhizosphere soil using Illumina MiSeq technology. Alpha and beta diversity analysis indicated that functionalized graphene increased the richness and diversity of bacteria and fungi in the <em>V. faba</em> rhizosphere peat soil. The abundances of three nitrogen cycling-related bacteria, <em>Hydrogenophaga</em>, <em>Sphingomonas</em> and <em>Nitrosomonadaceae</em>, were also altered after treatment with the functionalized graphene. The relative abundance of <em>Basilicum</em>, related to soil phosphorus solubilization, decreased in the fungal community, while the relative abundance of <em>Clonostachys</em> and <em>Dimorphospora</em>, which exhibited strong biological control over numerous fungal plant pathogens, nematodes and insects, increased in the soil after functionalized graphene treatment. Redundancy analysis revealed that the potential of hydrogen (pH), organic matter, and total phosphorus contributed the most to the changes in bacterial and fungal community composition in the rhizosphere soil. Overall, our findings suggested that the addition of functionalized graphene altered the relative abundances of nitrogen and phosphorus cycling-related microorganisms in peat soil, promoting changes in the physicochemical properties of the soil and ultimately leading to the improved growth of <em>V. faba</em> plants.</div></div>","PeriodicalId":19719,"journal":{"name":"New Carbon Materials","volume":"39 6","pages":"Pages 1227-1242"},"PeriodicalIF":5.7,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143311676","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}

Porous thin films of reduced graphene oxide containing SiC whiskers (SiC@RGO) for EMI shielding were prepared by a two-step reduction of graphene oxide (GO), in which the two steps were chemical reduction by HI and the solid phase microwave irradiation. A significant increase of the film thickness from around 20 to 200 μm was achieved due to the formation of a porous structure by gases released during the 3 s of solid phase microwave irradiation. The total shielding effectiveness (SE_<em>T</em>) and the reflective SE (SE_<em>R</em>) of the SiC@RGO porous thin films depended on the GO/SiC mass ratio. The highest SE_<em>T</em> achieved was 35.6 dB while the SE_<em>R</em> was only 2.8 dB, when the GO/SiC mass ratio was 4:1.

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.
