Surfactant-free synthesis and magnetic hyperthermia investigation of iron oxide (Fe3O4) nanoparticles at different reaction temperatures

Visible light-driven photocatalytic removal of water pollutants by a carbon-modified magnetically active ternary TiO2 (Fe3O4/carbon/TiO2) composite

“…The hysteresis loops indicate ferromagnetic behavior similar to the previous reports. 70,71 The saturation magnetization of Fe 3 O 4 was found to be 80 emu g −1 close to the literature values. 72,73 On the incorporation of carbon and TiO 2 , the magnetization values decrease simultaneously, however, the magnetization curves retain the same hysteresis loop nature.…”

The Influence of Synthesis Parameters on Structural and Magnetic Properties of Iron Oxide Nanomaterials

“…Magnetic iron oxide particles have been used for in vitro diagnostics for the past 40 years. Due to the unique physical, chemical, thermal and mechanical properties of iron oxide nanoparticles, as well as their biocompatibility and low toxicity in the human body, they have been used in many biomedical applications [1][2][3][4][5][6], such as contrast agents [7] for magnetic resonance imaging (MRI), carriers for controlled drug delivery and immunoassays [8][9][10][11][12][13], and also in magnetic hyperthermia [14][15][16][17][18][19][20][21][22][23]. All these applications require the particles to be superparamagnetic at room temperature.…”

Magnetite nanoparticles synthesized using grape fruit extract: synthesis, morphology, hyperthermia application and catalytic activity in hydrogen peroxide decomposition

“…Maghemite γ-Fe2O3 also has a spinel structure, but it contains cationic vacancies in the octahedral sublattice. Iron oxides are of great importance and widely used in catalysis [1,2], biomedicine [3,4], adsorption [5], photocatalysis [6,7] etc. Fe2O3 is used as a catalyst in the extraction of ammonia, as a component of ceramics, as a dye for cements and paints, as a carrier of analog and digital information [8].…”
