“Background In recent years, ceramic with nanostructures has AG-881 solubility dmso attracted a lot of attention and is being used in the fields of electronics, information LY3039478 cell line technology, and communications [1]. It has found wide application in other areas as well, including the mechanical and chemical sciences and electrical, optical, and electrochemical energy sectors as effective electrode materials [2, 3]. Among various chemical or physical synthetic

methods, the electrospinning method is a popular one and involves the use of an electrically charged jet of polymer solution to form the nanofibers. The method can be described as follows. A high voltage is applied to the ceramic material solution with a polymer, and an electric field is generated between the tip of the syringe containing the solution and the collector. The solution is ejected in the form of a jet by electrical repulsion onto the collector, and fibers of nanoscaled diameters with inorganic precursor Blasticidin S research buy are formed [4]. The precursor nanofibers at high temperature are calcined to remove the polymers, and ceramic phase is obtained. This technique has been applied for the preparation of various metal oxide and ceramic nanofibers as well [5, 6], which

included TiO2[7], ZnO [8], SnO2[9], BaTiO3[10], and Al2O3[2–6, 11]. Alumina (Al2O3) is one of the most important types of ceramic and is applied to the areas of catalysis, reinforcing components, electronic device fabrication, microelectronics, optics, and fire protection [12]. Most recently, alumina has been explored as effective electrode material for electrochemical energy storage device [13–15]. Al2O3 has specific physical, chemical, and mechanical properties, and during the process of forming the stable

α-Al2O3, gibbsite is transformed to boehmite and then to a variety of metastable intermediate structures such as χ-, γ-, κ-, δ-, θ-alumina, depending on the temperature [16, 17]. The main objective of the study is to investigate the calcination conditions on morphological appearance Glutamate dehydrogenase and crystal structure of the resulting alumina and the adsorption property of alumina calcined at different temperatures. Therefore, we investigated the synthesis of alumina nanofibers using a technique that combined the sol–gel and electrospinning methods using aluminum isopropoxide (AIP), an organometallic compound, as the precursor and polyvinylpyrolidone (PVP) polymer solution. The formation, morphology, and crystallinity of the electrospun alumina nanofibers were determined through thermogravimetric analysis (TGA), scanning electron microscopy (SEM), X-ray diffraction (XRD), and Fourier transform infrared (FT-IR) spectroscopy, Gas Chromatograph (Shimadzu GC-2010 Plus AF) and the alumina nanofiber samples synthesized were evaluated by nitrogen adsorption/desorption analysis. In addition, different phase alumina nanofibers were applied for the adsorption of methyl orange dye (MO) solution.
