“…PANI nanofibers of 50-80 nm in diameter prepared via a simple rapid mixing polymerization method were used as a highly effective reusable adsorbent for the removal of reactive black 5 (RB5) from aqueous solutions. 145 RB5 removal efficiency was slightly dependent on pH with the maximum removal obtained at pH = 2.0. The adsorption capacity increased with an increase in initial concentration of dye and temperature.…”

Polyaniline (PANI) nanofibers have enhanced water processibility and improved sensitivity and response time when exposed to chemical vapors, and unique advantages in other fields including electric devices and corrosion inhibition. Therefore, PANI nanofibers have attracted great interest and have potential for many commercial applications. In this paper, the advantages, formation mechanism, characteristics and factors influencing various methods for preparing PANI nanofibers are described in detail. Their conductive properties and mechanism are briefly introduced. Finally, the potential applications of PANI nanofibers are elaborated in many fields such as gas sensors, capacitors, electrode materials for cells, removal of contaminants from water, corrosion inhibition, enzyme immobilization, Schottky diodes, and so on. © 2018 Society of Chemical Industry

“…Recently, chemical reagents were usually used such as NaOH for reusability of dye‐adsorbed adsorbents, however, this would bring about the second pollution. In fact, thermal treatment also can regenerate ZnO‐Al 2 O 3 with Congo red dye , ZnO/CuO‐γ‐Al 2 O 3 with methyl orange .…”

In this study, mesoporous Al2O3@TiO2 nanocomposites were synthesized via two successive precipitation methods. Due to the coated TiO2 layer, the Al2O3@TiO2 exhibited a significantly enhanced efficiency for the removal of reactive black 5 dye (RB5). The morphology and compositional characteristics of Al2O3@TiO2 were investigated by TEM, HRTEM, XRD, EDS, FTIR, BET, and zeta‐potential analysis. TEM photos illustrated that TiO2 film covered Al2O3, XRD suggested compositional phases of γ‐Al2O3 and anatase TiO2, and BET measurement confirmed its characteristic of the mesoporous material. Al2O3@TiO2 was applied as an adsorbent to remove RB5 from aqueous solution, and the adsorption isotherms fitted well to the Langmuir isotherm model. The photocatalysis experiments confirmed that Al2O3@TiO2 had the good photocatalytic performance for degrading RB5 and the hydroxyl radical was the major active group. The UV–Vis adsorbance spectra demonstrated that this Al2O3@TiO2 could incompletely degrade RB5 dye under natural indoor light simultaneously when adsorption occurred. © 2018 American Institute of Chemical Engineers Environ Prog, 38: S230–S242, 2019

“…The important point is that PANI possesses large amounts of amine and imine groups which can interact with heavy metals and organic pollutants, making them suitable as a pollutant adsorbent from aqueous solution. As such, PANI and its composites have recently been used effectively for the removal of inorganic and organic pollutants from wastewater .…”

Evaluating the performance of citric acid as stabilizer and doping agent in an environment friendly approach to prepare electromagnetic nanocomposite particles

et al. 2017

The objective of this investigation is to find a less‐expensive and less‐toxic environmentally benign route for the preparation of magnetic PANI nanocomposite particles. For this citric acid, a weak organic tricarboxylic acid has been used during seeded chemical oxidative polymerization of aniline in presence of variable amounts of Fe3O4 nanoparticles. Nanosized Fe3O4 particles are first prepared by co‐precipitation of Fe2+ and Fe3+ from their alkaline solutions. Then in the second step, magnetic nanocomposite particles—named as Fe3O4/PANI—are prepared by seeded chemical oxidative polymerization of aniline using ammonium persulfate (APS) as oxidant. Independent of Fe3O4 content, Fe3O4/PANI nanocomposite particles possessed comparable high electrical conductivity having the same magnitude as HCl‐doped PANI particles (2.13 × 10−3 S/cm). This result suggested that addition of citric acid during seeded chemical oxidative polymerization not only promoted solubilization of aniline but also functioned as stabilizer and doping agent. Iron oxide content critically influenced the stability, morphology, and magnetic properties of the produced nanocomposite particles. The saturation magnetization and magnetic susceptibility increased with the increase of Fe3O4 content. The nanocomposite particles prepared with core/shell ratio of 0.6/1 (w/w) exhibited the strongest paramagnetism and aligned into fiber‐like structure. The analysis of electromagnetic properties and spectral data from FTIR, X‐ray diffraction (XRD), X‐ray photoelectron spectroscopy (XPS), and thermogravimetry (TG) confirmed the complete coverage of Fe3O4 nanoparticles by PANI layer.
