Synthesis of chitosan grafted-polyaniline/Co₃O₄ nanocube nanocomposites and their photocatalytic activity toward methylene blue dye degradation

Abstract

Co3O4 nanocube-doped chitosan-grafted-polyaniline nanocomposites have been successfully synthesised. The synthesised polymeric nanocomposite was stable and exhibits greater photocatalytic activity to degrade MB efficiently within a short duration of time.

Synthesis of Polyaniline coated Graphene Oxide @ SrTiO3 Nanocube Nanocomposites for Enhanced Removal of Carcinogenic Dyes from Aqueous Solution

“…Most of the synthetic dyes evade conventional water treatment methods, thereby accumulating in the environment due to their high degree of stability towards biodegradation, temperature, light, detergents, and soaps [8,9]. Methylene blue (MB) and methyl orange (MO), commercial dyes used for various applications such as textiles, papers, leathers, additives, laser printing, etc., are heterocyclic aromatic chemical compounds having complex chemical structures and synthetic origin, owing to which they are resistant to biodegradation and very stable despite light and oxidation [10][11][12]. These dyes are highly toxic, persistent, carcinogenic, and mutagenic in nature.…”

PANI-derived polymer/Al2O3 nanocomposites: synthesis, characterization, and electrochemical studies

“…The second weight loss occurred at higher temperature, from 230 to 430°C. It was assigned to loss of dopants from PANI [40]. The third weight loss from 430°C to 640°C was due to the decomposition of PANI chains themselves.…”

Functionality of TERGO Powders during the Synthesis of PANI-Based Composites for Electrical Devices

“…Figure 8 shows the UV-Vis spectra of the as-obtained composites and its comparison with pure PANI. Neat PANI have shown three main transitions, the first peak at around 360 nm is assigned to the π − π * transitions in benzenoid rings, the second at 450 nm, which is seen as a small transition, is also characteristic of polaronic transition (polaron π * ), and the last band appears at 820 nm and is attributable to the π polaron transition of quinoid rings through PANI chains [63,64].…”
