An in situ synthesis of a new nanocomposite, polyaniline/manganese dioxide/titanium dioxide (PANI/MnO2/TiO2), via a one-pot oxidative polymerization method at room temperature is described in this article. The characterization was done on the synthesized nanocomposite using UV–vis, FT-IR, XRD, TGA, SEM, and TEM analysis. A superior catalytic activity is exhibited by the synergistic PANI/MnO2/TiO2 nanocomposite in the conversion of toxic Cr6+ to benign Cr3+ in comparison with PANI, MnO2, TiO2, PA
A rapid way to dedye industrial effluents is reported herein using silver nanoshells (Ag-NSs) as a green catalyst.
A one-pot synthesis of rGO, AgNPs, rGO/AgNPs, AuNPs, rGO/AuNPs, Ag-AuNPs and rGO/Ag-AuNPs using <italic>Albizia saman</italic> leaf extract as a reducing and stabilizing agent is reported herein.
A novel gold–graphitic carbon nitride–polyaniline (Au@g-C<sub>3</sub>N<sub>4</sub>–PANI) nanoblend was synthesized <italic>via in situ</italic> oxidative polymerization of aniline using auric acid as an oxidant in the presence of g-C<sub>3</sub>N<sub>4</sub>.
A synthesis of novel sulfur and phosphorous co-doped graphitic carbon nitride (SP-g-C3N4) covalently grafted polyaniline (PANI) metal-free nanocomposite via an in situ oxidative polymerization is reported here. The nanocomposite was characterized by various instrumentation techniques such as UV-DRS, FT-IR, XRD, SEM, HR-TEM, EDX, and SEM mapping analysis. The as-prepared SP-g-C3N4-PANI metal-free nanocomposite shows an outstanding photocatalytic activity for the dedyeing of methylene blue (MB) un
The present work highlights a bio-inspired synthesis of uniform 2 nm sized plasmonic silver nanospheres (Ag-NSs) embedded in reduced graphene oxide nanosponge (RGONS) using <italic>Tabebuia berteroi</italic> leaf extract.
In the present work, in situ synthesis of polypyrrole-silver-polyvinylpyrrolidone (PPy-Ag-PVP) nanohybrid using AgNO<sub>3</sub> as an oxidant and polyvinylpyrrolidone (PVP) as a stabilizer and surfactant is demonstrated. The obtained ternary PPy-Ag-PVP nanohybrid was characterized by UV-vis, FT-IR, XRD, Raman, TGA, SEM, and HR-TEM analysis. Further the synthesized PPy-Ag-PVP has been investigated for its selective and sensitive sensing of dopamine (DA). The PPy-Ag-PVP modified glassy carbon ele
