“…Polydopamine (PDA) chemistry has emerged as an universal and efficient surface functionalization tool, which takes advantages of the strong adhesion of PDA . Due to the unique physicochemical properties and excellent biocompatibility of PDA, many potential applications of the PDA coated materials for diverse fields have been explored, such as biomedical applications and environmental applications . More importantly, PDA chemistry paves a new way for surface postmodification of the substrate due to high density of NH group or OH groups in the PDA coating .…”

Polymer brushes decorated reduced GO (rGO) with advanced applications have been prepared by bioinspired polydopamine (PDA) chemistry integrated with activators regenerated by electron transfer atom transfer radical polymerization (ARGET‐ATRP) technique. First, rGO/PDA was obtained by the process for graphene oxide (GO) coated with a homogeneous bio‐adhesive PDA layer. Then the initiator 2‐bromoisobutyryl bromide (BIBB) was immobilized on the surface of PDA functionalized rGO. Finally, rGO/PDA‐Br was polymerized with N, N‐diethylaminoethyl methacrylate (DEAEMA) and glycidyl methacrylate (GMA) to obtain rGO/PDA‐g‐polymer brushes by ARGET‐ATRP process. The prepared rGO/PDA‐g‐PGMA brush would be subjected to further functionalization with ethylenediamine (EDA), which would impart the obtained products (rGO/PDA‐g‐PGMA‐NH2) with good adsorption ability toward cationic dyes. The chemical structures and morphologies of the functionalized GO products have been characterized in detail by Fourier transform infrared spectroscopy (FTIR), X‐ray photoelectron spectroscopy (XPS), Raman spectroscopy, thermal gravimetric analysis (TGA), scanning electron microscope (SEM), transmission electron microscope(TEM), and atomic force microscopy (AFM). The distinctive pH‐responsive character of rGO/PDA‐g‐PDEAEMA and adsorption ability of rGO/PDA‐g‐PGMA‐NH2 for cationic dyes have been explored by UV–vis spectrophotometer. © 2018 Wiley Periodicals, Inc.

In this work, the fabrication of MoS 2 -Polyaniline (PANI) nanocomposites, by in situ polymerization, has been described and its application as a photocatalyst for the degradation of organic pollutants such as methylene blue (MB) and 4-chlorophenol (4-CP), has been reported. The disadvantages of MoS 2 such as poor electronic conductivity and agglomeration between the nanosheets, was overcome by intercalating 2D MoS 2 layers with 1D conducting polymer, Polyaniline (PANI). The composite material was characterised by SEM, TEM, BET, XRD, FTIR, UV-Vis spectroscopy and XPS, indicating proper intercalation between MoS 2 nanosheets and PANI. Consequently, the synthesized composites were used for the degradation of MB and 4-CP, followed by kinetic investigations to determine the rate kinetics. The photoactivity of the nanocomposite is explained by the transfer of photogenerated electrons from PANI to the CB of MoS 2 , thus preventing the direct recombination of electrons and holes. Hence, a positive synergistic effect between MoS 2 and PANI resulted in efficient photocatalytic degradation of organic dyes like MB.

“…Wide range organic and inorganic adsorbent has been used to reduce dyes from an aqueous solution such as chitin, chitosan 9 , cellulose 10 , bentonite 11 , kaolin 12 , clay 13 , carbon nanotube 14 , zeolite 15 , and also layered double hydroxide (LDH) [16][17][18] . LDH is inorganic layer material with the general formula [M 2+ /M 3+ (OH) ]x + [A n− ] •mH2O where M 2+/ M 3+ is divalent and trivalent metal ions, from stacking brucite-like layers metal oxide containing a positive charge due to partial substitution of divalent metal cation by trivalent metal cation 19 .…”

Layered double hydroxide (LDH) of Zn/Al and citrate-Zn/Al was prepared and used as an adsorbent of Congo red from aqueous solution. LDH was characterized by X-ray, FTIR, and BET analysis. Adsorption of Congo red was studied through kinetic, isotherm, and thermodynamic analyses. Zn/Al LDH has diffraction at 10.29o (003) with interlayer distance 8.59 Å and citrate-Zn/Al LDHs have anomalous diffraction at 7.57o (003) with interlayer distance 11.68 Å. The surface area of citrate-Zn/Al (40.50 m2 g-1) has higher than pristine LDH (1.97 m2 g-1). Adsorption of Congo red was conducted at pH 6 for Zn/Al LDH and at pH 8 for citrate-Zn/Al LDH. Adsorption of Congo red on both LDHs follows the pseudo-second-order kinetic model. The isotherm parameter follows the Freundlich isotherm model with maximum adsorption capacity 166.67 mg g-1 for Zn/Al and 249.99 mg g-1 for citrate-Zn/Al LDH. Adsorption of Congo red on both LDHs was classified as physical adsorption with energy 4.085-4.148 kJ mol-1.
