Evaluation of Fe³⁺fixation into montmorillonite clay and its application in the polymerization of ethylenedioxythiophene

Abstract

An analysis of the sorption process allowed to establish that Fe3+ sorption into montmorillonite is a chemical process that involves an exchange of cations from the montmorillonite interstitial space between layers.

Conducting Polymers in the Fields of Energy, Environmental Remediation, and Chemical–Chiral Sensors

“…The donor–acceptor conducting polymers, , which are in fact copolymers in the previous classification, the magneto-optical π-conjugated polymers, ,− which are organic or inorganic blends, and the composite materials have particularly enriched the field. Thus, classical CPs , are copolymerized, mixed with graphene, or charged with nanotubes, , clays, zeolites, montmorillonites, and other constituents yielding materials that combine the advantages of each component and exhibit special properties. In these composites, interfacial interactions and synergistic or complementary effects are present, and therefore special models have been developed to explain their conductivity .…”

Noncentrosymmetric Cu(II) Layered Hydroxide: Synthesis, Crystal Structure, Nonlinear Optical, and Magnetic Properties of Cu2(OH)3(C12H25SO4)

“…Layered materials have long proved to be materials of choice in the field of organic–inorganic hybrid systems. , Among these materials, one may quote layered oxalate, layered double or simple hydroxides (LDH or LSH), clays, , hexathiohypodiphosphates (MPS 3 ), , layered perovskite, or MX 4 -based layered perovskite-like materials . Hybrid materials based on these systems can have interesting properties in magnetism, ,,, ferroelectricity, multiferroicity, − magnetoelectricity, luminescence, , trapping of molecular species, , anticorrosion, or catalysis, for instance.…”

Cetylpyridinium bromide/montmorillonite-graphene oxide composite with good antibacterial activity

“…Note that the N 1s spectrum of GM-CPB (figure 3(c)) shows two peaks at 402.3 and 401.8 eV: the higher proportion at 402.3 eV corresponds to the corresponding peak of N 1s in the quaternary ammonium salt [38]. Similarly, the peaks at 102.61 and 103.42 eV in the Si 2p spectrum of the complex can be attributed to Si-O [39], demonstrating that the Si-O bond was obtained from MMT [40]. According to XPS spectra, the source and chemical composition of each element in GM-CPB was fitted and analyzed.…”
