Unprecedented Selective Oxidation of Styrene Derivatives using a Supported Iron Oxide Nanocatalyst in Aqueous Medium

Abstract

Iron oxide nanoparticles supported on mesoporous silica‐type materials have been successfully utilized in the aqueous selective oxidation of alkenes under mild conditions using hydrogen peroxide as green oxidant. The supported catalyst could be easily recovered after completion of the reaction and reused several times without any loss in activity (no metal leaching observed during the reaction), constituting a facile and straightforward example of aqueous oxidation chemistry promoted by iron‐based heterogeneous systems.

Precursor combustion synthesis of nanocrystalline cobalt substituted nickel zinc ferrites from hydrazinated mixed metal fumarates

“…Actually, the composition, cation distribution and particle size and shape are the important factors responsible for deviation in structural and magnetic properties [1][2][3][4] thereby opening doors of newer applications in various areas of interest such as sensing of toxic gases, medical field and in catalysis as magnetically recoverable catalyst for organic transformation [5][6][7][8]. Materials, especially magnetic ferrites are gaining attention of research groups from different fields due to their application from nanometric scale to bulk.…”

Highly ordered Nanomaterial Functionalized Copper Schiff Base Framework: Synthesis, Characterization, and Hydrogen Peroxide Decomposition Performance

“…For these reasons, and taking into account our recent results related to the design of immobilized catalysts for organic transformations such as oxidation reactions and carbon-carbon bond formations [42][43][44], we report herein the synthesis of a novel Schiff base tridentate copper complex immobilized on mesoporous nanomaterials, Cu-L@SBA-15. The synthesized Cu-L@SBA-15 was characterized by techniques including transmission electron microscopy (TEM), Fourier transform infrared spectroscopy (FT-IR), cross polarization magic angle spinning (CP-MAS), 13-carbon nuclear magnetic resonance ( 13 C-NMR), X-ray powder diffraction spectrometry (PXRD), atomic absorption spectroscopy (AAS) and thermogravimetric analysis (TGA).…”

Cobalt aluminate nanoparticles supported on MIL-101 structure: catalytic performance investigation

“…The nanoparticles were prepared through a non-aqueous sol-gel method following a recently published procedure. 32 The synthesis was carried out in a glovebox (O 2 and H 2 O < 1 ppm). Briey, in a glovebox, aluminium isopropoxide (2 mmol) was added to a cobalt acetate solution (1 mmol) in benzyl alcohol (20 mL) and allowed to stir for 10 min at room temperature.…”
