Facile in situ synthesis and characterization of a novel PANI/Fe₃O₄/Ag nanocomposite and investigation of catalytic applications

Abstract

A novel magnetic hybrid nanocomposite was successfully synthesized via in situ polymerization, well characterized by FT-IR, XRD, EDX and FE-SEM analysis, and its catalytic activity shown in the synthesis of pharmaceutically important pyrans.

Synthesis and crystal structure of a new copper (II) complex, designed to produce efficient successor of Cu2O, toward synergy of adsorption and photodegradation of MB

“…Previously, Rabbani et al 80 reported efficient removal of MB using catalysts of Ag–TiO 2 and Zn‐TCPP/Ag–TiO 2 under UV and visible light irradiation. They found that both synthetic catalysts have higher catalytic activity under UV light than the visible light and removal efficiency of MB reaches the maximum value of 100% for both catalysts 81–85 . Table shows the maximum removal of adsorption and photodegradation of MB by some catalyst 86–90 …”

Green synthesis of silver nanoparticles using Eucalyptus comadulensis leaves extract and its immobilization on magnetic nanocomposite (GO‐Fe3O4/PAA/Ag) as a recoverable catalyst for degradation of organic dyes in water

“…[6][7][8][9][10][11] The agglomeration of nanoparticles during the catalytic reaction is one of their disadvantages. [12][13][14][15][16] Separation of nanoparticles from the reaction medium using simple methods such as filtration and centrifugation is difficult. [17][18][19][20] To overcome these difficulties, different solid supports such as TiO 2 , graphene, mesoporous materials, and Fe 3 O 4 were applied for the immobilization of metal nanoparticles and the construction of the heterogeneous nanocatalyst.…”

Copper Schiff base functionalized polyaniline (Cu‐SB/PANI): A highly efficient polymer based organometallic catalyst for the synthesis of 2‐amino chromene derivatives

“…Among conducting polymers, polyaniline (PANI) is one of the most preferred conjugated polymers due to its low price and availability, easy synthetic procedure, tolerance to a wide range of reaction conditions and interesting redox properties associated with the nitrogen atom in the polymer backbone. Polyaniline has been used as a support material because of its unique properties such as easy synthesis from readily available starting material (aniline), higher stability and non‐solubility in common organic solvents . Some of the reported PANI based catalysts used for various organic transformations such as Mizoroki‐Heck Cross‐Coupling reaction, methanol oxidation, epoxidation of peptides, epoxidation of alkene, Biginelli reaction, and oxidation of alcohols are given in Figure .…”
