Synthesis of Fe₃O₄ Nanoparticles using PEG Template by Electrochemical Method

One-step synthesis of γ-Fe2O3/Fe3O4 nanocomposite for sensitive electrochemical detection of hydrogen peroxide

“…After a few minutes of the electrosynthesis the reaction media displayed a light brown color as a result of iron hydroxide (III) or ferric oxyhydroxide FeOOH (6) formation ( Fig. 4 a) [64] :…”

“…The chemical interaction of ferric oxyhydroxide obtained by ( 6) and ( 7) and iron hydroxide (II) in solution is actual route of magnetite F e 3 O 4 formation (8) [64] : An intense hydrogen bubbling (4) occurs via water reduction during the cathodic pulse and causes the electrode potential increase at the pulses due to ohmic losses ( Fig. 4 b) and electrolyte heating ( Fig.…”

Magnetic Nanoparticle Composites: Synergistic Effects and Applications

“…Ag‐Fe 3 O 4 nanocomposites have been synthesized by a combination of electrochemical and reduction methods: in particular, the electro‐oxidation of iron in water was used, and Ag + was reduced to Ag 0 with glucose as reductant and NaOH as accelerator. [ 1 ] In fact, magnetite nanoparticles have been used as cores to be coated also by other inorganic materials, apart from gold. For example, an uncomplicated and green approach to produce core–shell Fe 3 O 4 @C@MnO 2 composites was reported.…”

“…The states of the nanocomposites can be colloidal, powder, fibers, membranes, or films. [ 1 ] For example, carbon shells and graphene sheets combined with Fe 2 O 3 nanoparticles have been reported to provide electrical networks that allow fast and efficient electron transport, when these composites are used as anode materials in Li‐ion batteries. Carbon coating around each individual iron oxide nanoparticle hinders the direct contact of electrode and electrolyte, thus endowing a large reversible specific capacity to the whole composite material.…”
