摘要:以价格低廉的Fe3O4纳米颗粒为填料,聚(3,4-乙烯二氧噻吩):聚(苯乙烯磺酸)(PEDOT:PSS)为基材制备复合材料,并采用高氯酸(HClO4)对其进行后处理,获得PEDOT:PSS/Fe3O4柔性自支撑薄膜。利用扫描电子显微镜(SEM)、X-射线衍射仪(XRD)、X射线电子...
The Raman spectrum has two distinguishable peaks of 1340 cm−1 and 1580 cm−1, corresponding to the D-band and G-band, which reveal the degree of graphitization of the carbon shell [46]. The intensity ratio (ID/IG) of the SP Fe3O4@C is 0.869, 0.842 and 0.835, respectively, ...
Figure1. (d) Long-term stability of Na-ZnFe@C catalyst. Reaction conditions: 320 oC, 5 MPa (23.8% CO2, 71.2% H2, and 5.0% Ar), 15 mL min-1, and time on stream (TOS) = 24 h. Catalyst weight: Fe-based catalyst of 0.1 g and quartz sand of 1 g. Figure S1. The Raman sp...
Fe3O The Raman spectrum of SP-Fe3O4-C displayed two peaks attributed to theG(1589 cm−1) andD(1345 cm−1) bands (Supplementary Fig.8b)59. A highG/Dband intensity ratio (IG/ID~ 1.2) indicated a high degree of graphitization of the carbon framework, which favors electrical ...

The results obtained from the Raman spectrum showed the presence of magnetite with amine groups. Ligand coupled magnetic nanoparticle affinity matrices were developed successfully by coupling the Fe3O4 magnetic nanoparticles to phosphomannan (PMC) oligosaccharide and lactose separately using DVS as the ...

Here, a rapid, ultra-sensitive, magnetic-assisted biosensor based on resonance Raman scattering at MoS2@Fe3O4 composite nanoflowers is presented. Raman shifts and X-ray photoelectron spectra indicated that the composite was formed via Fe–S covalent bonds. Convenient magnetic separations could be ...
A series of modes could be detected in the amplified Raman spectrum of GCF1 including the D and G band located around 1405 cm−1 and 1570 cm−1 respectively. The peaks corresponding to the CH3 bending (scissor deformation, 1449 cm−1) from amide 2 N–H deformation (1544 ...
The O 1s spectrum of Fe3O4 NPs displays a maximum peak centred at 529.8 eV which is ascribed to the Fe–O bonds. This finding can be substantiated by the fact that the formation of metal–O–C bonds in nanocomposites could be shifted to higher binding energy approxi- mately 1–3 eV ...
