Abstract The development of a nonprecious, stable, and highly effective electrocatalyst for decomposition water into oxygen hydrogen is vitally important sustainable energy conversion, but it still remains challenging to replace the noble metal electrocatalysts with more economically viable alternatives. Herein, polyaniline (PANI) decorated hierarchical nickel cobalt thiospinel (NiCo 2 S 4 ) hy...

This study aims at exploring an effective route in the in situ graft polymerization of aniline from Fe3O4 nanoparticles. To this goal, Fe3O4 magnetic nanoparticles were prepared by coprecipitation method using ammonia solution as the precipitating agent, and were characterized by Fourier transform infrared (FT-IR) spectroscopy, X-ray diffraction (XRD) and transmission electron microscopy (TEM)....

The aniline dimer, N-(4-aminophenyl)aniline has been polymerized cleanly under mild conditions to obtain an emeraldine base form of polyaniline using [MeB(3-(Mes)Pz)3]CuCl as the catalyst and H2O2 as the oxidant, while the subsequent acidification of the emeraldine base gives the conducting emeraldine salt form of polyaniline.

A new mechanism for the formation of doped polyaniline is presented. Besides providing suitable structural and spectroscopic parameters, the new mechanism allows for the rationalization of the experimentally observed equilibrium between polaron and bipolaron defects in emeraldine salt. The magnetic behavior and the "metallic island" model for conduction in doped polyaniline are also theoretical...

Polyaniline nanocomposite using metal oxides have wide variety of applicability because its enhanced properties to that pure polyaniline. Here we employed titanium dioxide as the oxide synthesize polyaniline composite (PANi-TiO2 ) through chemical oxidative polymerization in-situ. The obtained PANi-TiO2 is tested for powder X-Ray diffractometry (XRD), & Scanning electron microscopy(SEM).

Hierarchical materials have been considered promising for secondary battery electrodes owing to their capability of accommodating volumetric change active and providing short pathways rapid transportation ions electrons. Herein, we present a rod-on-tube composite consisting cobalt molybdate (CoMoO4) nanotubes coating with polyaniline (PANI) hydrogel nanorods, which exhibits high electrochemical...
