Sandwich-structured graphene–NiFe2O4–carbon nanocomposite anodes with exceptional electrochemical performance for Li ion batteries
Graphene–NiFe2O4–carbon nanocomposites with a sandwich structure are synthesized via the hydrothermal growth of NiFe2O4 nanoparticles on graphene sheets, followed by carbon coating. As a promising anode material for Li ion batteries...
NiFe2O4/graphene nanocomposites with tunable magnetic properties
Novel NiFe2O4/graphene nanocomposites were synthesized via facile,one-pot solvothermal route,and the effects of processing conditions and composition on their magnetic properties have been studied.The nanocomposites consisted of monolayer graphene...
Silica coated magnetic NiFe2O4 nanoparticle supported phosphomolybdic acid; synthesis, preparation and its application as a heterogeneous and recyclable catalyst for the one-pot synthesis of tri- and tetra-substituted imidazoles under solvent free conditi
In this research, a magnetically-recoverable catalyst (NiFe2O4@SiO2–H3PMo12O40) was prepared by
supporting phosphomolybdic acid (H3PMo12O40) onto silica-coated NiFe2O4 nanoparticles. The prepared
sample was characterized by FT-IR, TEM...
Polyphosphoric acid supported on silica-coated NiFe2O4 nanoparticles: An efficient and magnetically-recoverable catalyst for N-formylation of amines
A rapid, green and simple method for the N-formylation of various aromatic amines with
formic acid using polyphosphoric acid supported on silica-coated NiFe2O4 magnetic
nanoparticles (NiFe2O4@SiO2–PPA) under solvent-free conditions...
A facile hydrothermal synthesis of novel hollow triple-shell CuNiFe2O4 nanospheres with robust catalytic performance in the Suzuki–Miyaura coupling reaction
dissolved in water together with glucose, and the mixture was heated to 180 0C in an autoclave. Finally, the carbon core was removed by calcination at 550 0C. The triple-shell hollow
spheres of CuNiFe2O4 were characterized by XRD, TEM, FE-SEM, and EDS...
Synthesis, characterization and first application of keggin-type heteropoly acids supported on silica coated NiFe2O4 as novel magnetically catalysts for the synthesis of tetrahydropyridines
In this study, two heteroploly acids with Keggin structures (phosphotungestic acid (PWA) and
phosphomolybdic acid (PMA)) have been supported on silica coated nickel ferrite nanoparticles
(NiFe2O4@SiO2). The synthesized catalysts were...
One-pot Synthesis of 1-Amidoalkyl-2-naphthols Catalyzed by Polyphosphoric Acid Supported on Silica-coated NiFe2O4 Nanoparticles
we describe here a simple, mild and efficient procedure for the one-pot three-component synthesis of
1-amidoalkyl-2-naphthols from 2-naphthol, various aldehydes, and amides (benzamide,
acetamide or urea) using NiFe2O4@SiO2–PPA...
