A bonding method was developed for coating molybdenum oxides onto a steel wire substrate, which was used as a solid‐phase microextraction fiber, was coupled with gas chromatography. Based on the characterization, it is found that the as‐prepared molybdenum oxides material contained a nanobelt structure with a uniform size and good dispersibility. In addition, there were a large number of small protrusions on the surface of the nanobelts. These characteristics provided a large specific surface area for extraction. Molybdenum oxides exhibited a high extraction selectivity for polycyclic aromatic hydrocarbons owing to its moderate coordination. After the optimization of the factors, method detection limits of < 1.25 μg/L were achieved, and the calibration curves were linear within the range of 2–600 μg/L. In addition, repeatability was demonstrated, and the relative standard deviation < 6.4%. The molybdenum oxides coating had a high scratch resistance, which could effectively prevent coating wear and failure. Combined with the high thermal and chemical stability, the service life of the coating was improved and could be used 150 times without a significant reduction in the extraction performance. Finally, the as‐prepared fiber had a comparable extraction capacity and higher partition coefficients that those of commercial polyacrylate fibers.

“…The values of the correlation coefficient obtained were between 0.987 and 0.996, showing an acceptable linearity in the dynamic ranges. In comparison to other coating materials in the literature, such as CNTs sol-gel, carbon, PEG-g-CNTs, MIL-101 (Cr), Vinyl-SBA-15, ZNRs/PANI, cobalt oxide nanoparticles, [30][31][32][33][34][35][36] for the extraction and determination of BTEX, the proposed ber (PA@Fe 3 O 4 nanocomposite) shows a suitable limit of detection (Table 2). In addition, a ber with a polyaniline coating was tested for comparison with a PA@Fe 3 O 4 coating for the microextraction of BTEX.…”

“…The study of cobalt nanoparticles and its oxide have attracted many interests, for example, Li et al [18] have prepared Co films by thermal evaporation and have studied the effect of in situ high magnetic field on the films. Gholivand et al [19] have synthesized cobalt oxide nanoparticles by chemical bath deposition on a Pt wire in order to fabricate a novel solid phase micro-extraction fiber coating. The synthesis of mono-dispersed cobalt nanocrystals by chemical method was also reported by Bao et al [20].…”

Cobalt/carbon nanocomposite coating (Co NPs @ a-C: H), which consist of cobalt nanoparticles buried in hydrogenated amorphous carbon are prepared by RFsputtering and RF-plasma enhanced chemical vapor deposition on silicon substrates. In these processes, the coatings are produced from a cobalt sputtered target and acetylene reactant gas. The crystalline structure and surface topography of the deposited films are characterized by X-ray diffraction (XRD) and atomic force microscopy (AFM), respectively. The AFM shows that the average size distribution depends on the deposition conditions and RMS varies from 3.5 up to 6 nm. The XRD analyses indicate the presence of cobalt nanostructure as centered face cubic phase and its oxide, but with no evidence of carbide structure. The energy-dispersive X-ray spectroscopy analysis was used to identify the elements composition in the films and the ultraviolet-visible spectrophotometry is used to study surface plasmon resonance bands of Co nanoparticles.
