“…Nanostructured metal oxide coatings could be readily prepared by anodizing metal wires. Aluminum oxide was one of the most studied coating materials; under different anodizing conditions, different morphologies were obtained [176][177][178][179]. Zhang et al [179] even coupled chemical etching to anodization to prepare a nanowire coating.…”

The basic principles for the preparation of SPME fibers with satisfying selectivity, sensitivity, loading capacities and stabilities are summarized here in terms of the physicochemical properties of the coating materials and the supporting substrates of SPME fibers. While the main part of this chapter focuses on the advances in developing the most widely used coating materials, including ionic liquids, polymeric ionic liquids, carbonaceous materials, molecularly imprinted polymers, metal-organic frameworks, metals and metal oxides, conductive polymers, modified silica, as well as their composites, into SPME fibers. Meanwhile, the applications of novel SPME fibers in analyzing diverse analytes in different sample matrices are briefly reviewed, including the emerging applications of SPME in the extraction of bioactive compounds in living animals and plants.Keywords SPME fiber coating Á Ionic liquid Á Polymeric ionic liquid Á Graphene Á Carbon nanotube Á Molecularly imprinted polymer Á Metal-organic framework Á Metal and metal oxide Á Conductive polymer Á Modified silica IntroductionThe outstanding features of solid-phase microextraction (SPME), including rapid and simple operating procedures, slight disturbance to investigated systems, reduced consumption of solvents, and feasibility of automation, continuously inspire new explorations of SPME in various frontiers, such as metabolome detection [1], central nervous systems studies [2], pharmacokinetic studies [3], environmental analysis [4], and food analysis [5].

“…In addition, some task-specific SPME coatings such as molecularly imprinted polymers [5][6][7][8], conducting polymers [9][10][11][12], ionic liquids [13][14][15][16], sol-gel materials [17][18][19], biosorbents [20,21], and nanomaterials (NMs) [22][23][24] with enhanced extraction efficiency, selectivity, and chemical stability were developed to accomplish the extraction of a wide range of analytes in different matrixes. Among the tested SPME coatings, NMs including metal and metal oxide nanoparticles [25][26][27][28], metal-organic frameworks [29][30][31], siliceous NMs [32,33], and carbonaceous NMs (CNMs) [34] have received much attention due to their unique physicochemical properties. CNMs, as a member of NMs, have emerged as a robust alternative to commercial coatings in virtue of its remarkable electronic properties, excellent mechanical strength and thermal stability [22,23].…”

“…However, high cost of production has limited its application. Some authors have reported synthesis methods of low-dimensional nano alumina successfully, mainly including solid-phase method, vapor-phase method [16], and liquid-phase method [17, 18]. Among them, the liquid-phase method is applied widely for its mild reaction condition, homogeneous products, and low cost of production.…”

Alumina nanorods were prepared from chromium-containing alumina sludge, and the effects of doping elements, such as Cr, Fe, and Mg, were researched. The results show that the crystal transformation of alumina is restricted by the doped Cr and facilitated by the doped Fe and Mg, which is transformed from θ-Al2O3 to α-Al2O3 in the calcination process. Meanwhile, the crystal transformation of alumina is strongly restrained by co-doped elements from the chromium-containing alumina sludge. The doped elements change the course of phase structure transformation and slightly transform the chemical bond of the alumina nanorods. The impure elements are doped in the alumina crystal and restrain the crystalline growth of alumina nanorods according to the rules. In the sample prepared from chromium-containing alumina sludge, more Cr and Mg but fewer Fe are doped, and most Cr are existed as Cr(III). It is possible that the Fe-doping is confined by the competition of Cr and Mg. Moreover, the lattice imperfection of alumina is caused by doped ions, such as Cr, Fe, and Mg, and the chemical state of O and Al are affected. The findings by these experiments provide essential information for eliminating pollution and promoting comprehensive utilization of the chromium-containing alumina sludge.
