“…The catalytic performances of different catalytic systems for the oxidation of PhCH 2 OH to PhCHO with H 2 O 2 in water or solvent‐free systems were compared in Table . The yield of PhCHO achieved in the simple Fe 3 O 4 /C 3 H 8 O 3 catalytic system was comparable to or better than those obtained with other magnetic iron oxides (Table , entries 1–6) . However, it was still lower than those obtained with other heterogeneous catalysts with higher surface areas (e.g.…”

BACKGROUND Hydrogen peroxide (H2O2) has been used widely in diverse areas of biotechnology, environmental remediation and organic synthesis wherein its catalytic activation to generate reactive oxygen species (e.g. hydroxyl radicals) is of vital importance. Magnetite (Fe3O4) microspheres are attractive heterogeneous peroxidase‐like catalysts due to many technological advantages (e.g. biocompatible, stable and magnetically recoverable). However, its peroxidase‐like activity has to be improved for practical applications. RESULTS Small amounts of short‐chain saturated alcohols (e.g. methanol, ethanol, iso‐propanol, tert‐butanol, mono‐ethylene glycol and glycerol) increased collision frequency between H2O2 and Fe3O4 (e.g. by about two orders of magnitude with the addition of 1 mol% glycerol) via facilitating the nucleophilic addition of H2O2 to surface Fe sites and promoted Fe3O4‐catalyzed decomposition of H2O2 and selective oxidation of benzyl alcohol with H2O2 in water. In addition, Fe3O4 microspheres were magnetically recoverable and reusable for at least five times without loss of catalytic activity and selectivity. CONCLUSIONS The Fe3O4/trace alcohol catalytic system decomposed H2O2 effectively. Its potential application was demonstrated by selective oxidation of benzyl alcohol with H2O2 in water in this work. This simple and efficient catalytic system may be applied also to other oxidative transformations in organic syntheses, or to oxidative degradation of organic pollutants in environmental remediation. © 2019 Society of Chemical Industry

“…FeNps is highly potential to be used in biosensor, catalytic, optical, electrical, biomedical and magnetic applications [1][2]. Moreover, these FeNps is easy to synthesize, environmental friendly in a certain quantity and inexpensive [3]. Various techniques have been developed and established for synthesizing FeNps, however some of the techniques proposed apparently not suitable to produce FeNps in large quantity [4].…”

Abstract. This study focuses on hydrogel as nano template to produce iron nanoparticles (FeNps). Radical polymerization was used to synthesize the hydrogel from nata de coco (NDC-g-PAA). Ferrocenium (FcCL) with 1 x 10 -4 g/ml has successfully incorporated with NDC-g-PAA hydrogel system and reduce using sodium hydroxide (NaOH) at different concentrations. Transmission electron microscopy (TEM) result demonstrates that the size of FeNps produced was about 5 -20 nm. Morphological analysis of hydrogel is carried out by scanning electron microscopy (SEM), SEM-EDEX is used to determine percentage of iron (Fe) in hydrogel. The results offer a wide range of application in various areas, especially the use of hydrogel system as a responsive template.

“…Continuous efforts have been made to reduce size of the particles with a simultaneous focus on preserving and enhancing the dispersion, in order to improve the quality and affordability of these iron-based catalysts. Several attempts have been made to prepare iron oxides and explore their catalytic activities in petrochemical industries [1][2][3][4][5][6][7][8][9]. Research has established the enhancing effect of promoters on the catalytic activity of iron-based catalysts, for example, molybdenum promotes the catalytic activity of sulfated hematite while tungsten has additive effect when used in combination with molybdenum.…”

Iron oxide nanoparticles supported on zirconia were prepared by precipitation-deposition method and characterized by XRD, SEM, FT-IR, TGA/DTA, surface area and particle size analysis. Catalytic activities of the catalysts were tested in the gas-phase conversion of cyclohexanol in a fixed-bed flow type, Pyrex glass reactor, at 433 -463 K. Major detected products were cyclohexanone, cyclohexene and benzene, depending on the used catalyst. The rate of reaction was significantly raised by the introduction of molecular oxygen in the feed gas, thereby suggesting the oxidation of cyclohexanol to cyclohexanone. Furthermore, the catalytic activity of iron oxide nanoparticles supported on zirconia treated with hydrogen at 553 K for 2 hours, was more selective and better than the unreduced iron oxide nanoparticles supported on zirconia, in the gas-phase oxidation of cyclohexanol to cyclohexanone. Experimental results showed that there was no leaching of metal, and that the catalyst was thus truly heterogeneous.
