A new generation photocatalyst CuFe2O4/rGO/halloysite nanotube (HNT) was manufactured using a simple procedure in this work. Material characterisation results reveal that the CuFe2O4 active phase with size of around 30-40 nm is spread rather consistently across sandwich-like structure rGO/HNT. The material's bandgap energy 1.9 eV, which boosts capacity to function even visible light area. catal...

Maghemite (γ-Fe2O3) nanoparticles were obtained by coprecipitation of ferrous and ferric salts in an alkaline medium followed by oxidation; the nanoparticles were coated with poly(N,N-dimethylacrylamide) (PDMA) and characterized by transmission electron microscopy, attenuated total reflection (ATR) Fourier transform infrared (FTIR) spectroscopy, dynamic light scattering, thermogravimetric and e...

in this paper cufe2o4, nanocrystalline powders were prepared. also, the supported cu ferrite was obtained by impregnation of the supports with cu and fe nitrates solutions, for calcination temperature 450 ºc. the samples were characterized by x-ray powder diffraction (xrd) and fourier transform-infrared spectroscopy (ft-ir). in this investigation photocatalytic degradation of acid red 206 in wa...

Tailoring highly efficient adsorbents for environmental remediation is a great challenge key. This paper reports the synthesis of nanostructured pure hydroxylapatite and hydroxyapatite coupled with copper ferrite CuFe2O4@HAp by simple routes utilizing in capture some heavy metal ions like Fe(II) Al(III) ions. The prepared has advantage feasible removal adsorbent materials after treatment proces...

A dual catalyst containing Pd and CuFe(2)O(4) nanoparticles in a silica shell exhibits >98% conversion of arylacetylenes to related styrenes with selectivity greater than 98%, which are better than those obtained using a commercial Lindlar catalyst. The excellent synergy was likely a result of the proximal interaction between Pd and CuFe(2)O(4) nanoparticles.

In this work, we proposed to synthesize CuFe2O4/Fe2O3 core-shell materials with different Fe2O3 contents in order create new and efficient photo-Fenton-like catalysts for the degradation of methylene blue oxalic acid as a radical-producing source. The were prepared through two stages: first, CuFe2O4 was by hydroxide coprecipitation – annealing method then, immobilized on surface simple impregna...
