Electrochemical in situ fabrication of titanium dioxide-nanosheets on a titanium wire as a novel coating for selective solid-phase microextraction

Phenyl-functionalization of titanium dioxide-nanosheets coating fabricated on a titanium wire for selective solid-phase microextraction of polycyclic aromatic hydrocarbons from environment water samples

“…TiO 2 NS coating can be in situ fabricated on a Ti wire by electrochemical anodization in ethylene glycol containing 10% (w/w) NH 4 F [34]. Temperature has a significant effect on the morphology of TiO 2 NS.…”

“…Jiang and co-workers also fabricated a well-aligned TiO 2 nanotube arrays coated fiber through anodizing a Ti wire substrate for selective SPME of polycyclic aromatic hydrocarbons (PAHs) [33]. Similar method was employed to in situ fabricate a novel TiO 2 -nanosheets coated fiber by electrochemical anodization of Ti wire substrates for efficient and selective SPME of ultraviolet (UV) filters in water [34]. The TiO 2 -nanosheets were cross-linked and tightly embedded into the Ti wire substrate.…”

Development of Novel Solid-Phase Microextraction Fibers

“…Zhang et al [179] even coupled chemical etching to anodization to prepare a nanowire coating. Similarly, zinc wire and titanium wire were also anodized to prepare ZnO and TiO 2 coatings [180,181]. After TiO 2 coating formed by anodizing, phenyl groups could be subsequently functionalized on TiO 2 for extracting PAHs through π-π stacking effect [182].…”

Growth of cedar-like Au nanoparticles coating on an etched stainless steel wire and its application for selective solid-phase microextraction

“…Currently SPME has been considered as one of the most attractive methods for sample preparation of analytes in environmental [2], food [3], pharmaceutical [4] and biological [5] samples due to its simplicity, rapidity, sensitivity and easy quantification. In SPME, the fiber comprises a supporting substrate and a surface sorbent coating.…”
