Poly(vinyl alcohol) Embedded with Montmorillonite Clay and Nano Titania: A Scale-Up for Sustainable Environmental Remediation.

A poly(vinyl alcohol)/montmorillonite/titania (PVA/MMT/TiO) nanocomposite film was fabricated via a simple solution casting strategy for the removal of cationic as well as anionic dyes. The developed nanocomposite film was subjected to X-ray diffraction (XRD), Fourier transform Infrared (FTIR), thermogravimetric analysis, dynamic mechanical analysis (DMA), mechanical property evaluation, and scanning electron microscopy (SEM) analysis. The embedding of MMT and TiO nanoparticles onto a PVA matrix has been confirmed from XRD, FTIR, and SEM analysis.

Polyindole-Derived Nitrogen-Doped Graphene Quantum Dots-Based Electrochemical Sensor for Dopamine Detection.

The sensitive monitoring of dopamine levels in the human body is of utmost importance since its abnormal levels can cause a variety of medical and behavioral problems. In this regard, we report the synthesis of nitrogen-doped graphene quantum dots (N-GQDs) from polyindole (PIN) via a facile single-step hydrothermal synthetic strategy that can act as an efficient electrochemical catalyst for the detection of dopamine (DA). The average diameter of N-GQDs was ∼5.

Surface basicity mediated rapid and selective adsorptive removal of Congo red over nanocrystalline mesoporous CeO.

Herein we first report surface basicity mediated rapid and selective adsorptive removal of organic pollutants over nanocrystalline mesoporous CeO. The role of surface features in controlling the selectivity and efficiency of adsorption is well known. Nevertheless, the possibility of tuning the adsorption capacity and selectivity of adsorbents through their surface characteristics remains less explored.

Ternary 3D reduced graphene oxide/NiZnFeO/polyindole nanocomposite for supercapacitor electrode application.

A facile two-step strategy has been reported for the preparation of a ternary 3D reduced graphene oxide/NiZnFeO/polyindole nanocomposite (GNP) and this composite is applied as an electrode material for supercapacitor applications. Remarkably, NiZnFeO nanoparticles (NZF) decorated on reduced graphene oxide (GN2) are achieved by a facile hydrothermal method followed by coating with polyindole (PIN) through an emulsion polymerization process. The structure, porosity, morphology, and thermal stability of the resulting ternary GNP hybrid material were characterized X-ray diffraction (XRD), Raman spectroscopy, Brunauer-Emmett-Teller (BET) surface area measurements, transmission electron microscopy (TEM), and thermogravimetric analysis (TGA).
