Facile Synthesis of Iron Oxide/Graphene Nanocomposites Using Liquid Phase Plasma Method

Abstract

Liquid phase plasma (LPP) method was applied, for the first time, to the impregnation of iron oxide nanoparticles onto graphene sheet. Iron oxide nanoparticles with the size of 50 nm were precipitated with uniform dispersion on the surface of graphene sheet. The amount of iron oxide nanoparticles precipitated on graphene sheets increased with increasing LPP process times. The XPS, Raman and EDX analyses showed that the iron oxide/graphene composites synthesized by the LPP process.

Entropy-stabilized metal oxide nanoparticles supported on reduced graphene oxide as a highly active heterogeneous catalyst for selective and solvent-free oxidation of toluene: a combined experimental and numerical investigation

“…Besides, the two bands at 1336 and 1592 cm −1 are related to the disorder-induced phonon mode (D-band) and graphitic lattice mode (G-band) of carbon attributed to the sp 2 atoms. 49 The sp 2 domain extensions are inversely proportional to the ratio of I D / I G . The I D / I G > 1 shows that the metal oxide nanoparticles anchored onto rGO disordered sheets.…”

Tribological analyses of a new optimized gearbox biodegradable lubricant blended with reduced graphene oxide nanoparticles

“…The peaks at 387 cm −1 and 1276 cm −1 indicated the presence of hexanoic acid 82 on the steel surfaces from the degradation of vegetable oils. The presence of peaks at 452 cm −1 and 1586 cm −1 indicated the formation of secondary oxides such as iron oxide 83,84 and a tribo protection film by r-GO. 85 These stable films prevented metal to metal contact by furnishing a superior contact film over the asperities at the contact surface.…”

Liquid Phase Plasma Synthesis of Iron Oxide Nanoparticles on Nitrogen-Doped Activated Carbon Resulting in Nanocomposite for Supercapacitor Applications

“…Two methods for nitrogen doping have been reported: carbonization of abundant nitrogen such as polypyrrole from nitrogen-containing precursors [ 23 , 24 ] and introducing nitrogen-containing reagents such as ammonia, urea, amines, and melamine to the carbon matrix [ 25 , 26 , 27 ]. Recently, the plasma generated from the liquid phase has been used to synthesize metal oxide nanoparticles, which were then impregnated with carbonaceous materials [ 28 , 29 , 30 ]. In previous studies, carbon composites impregnated with metal oxide nanoparticles were synthesized using a liquid phase plasma (LPP) method and applied to EDLCs [ 31 , 32 , 33 ].…”
