“…Nanoscale materials have remarkable optical, magnetic, electrical, and catalytic properties [ 1 , 2 , 3 , 4 , 5 , 6 ]. The structure and composition of spinel nano-ferrites control the functional properties of magnetic nanosized materials [ 4 , 5 ]. Nanocomposites (NCs) are mixtures of different components at the nanometer scale, with properties that depend on the contribution of each component in the mixture [ 5 ].…”

This paper presents the influence of Mn2+ substitution by Ni2+ on the structural, morphological and magnetic properties of Mn1−xNixFe2O4@SiO2 (x = 0, 0.25, 0.50, 0.75, 1.00) nanocomposites (NCs) obtained by a modified sol-gel method. The Fourier transform infrared spectra confirm the formation of a SiO2 matrix and ferrite, while the X-ray diffraction patterns show the presence of poorly crystalline ferrite at low annealing temperatures and highly crystalline mixed cubic spinel ferrite accompanied by secondary phases at high annealing temperatures. The lattice parameters gradually decrease, while the crystallite size, volume, and X-ray density of Mn1−xNixFe2O4@SiO2 NCs increase with increasing Ni content and follow Vegard’s law. The saturation magnetization, remanent magnetization, squareness, magnetic moment per formula unit, and anisotropy constant increase, while the coercivity decreases with increasing Ni content. These parameters are larger for the samples with the same chemical formula, annealed at higher temperatures. The NCs with high Ni content show superparamagnetic-like behavior, while the NCs with high Mn content display paramagnetic behavior.

“…Binary materials are of outstanding quality including high melting points, high hardness, low temperature coe cients, low density, high stability of chemicals, high thermal conductivity, high expansion, as well as better mechanical qualities such as increasing resistance to wear, high speci c resistance and special modulus. [9][10][11][12][13][14][15]. The intense interactions between the binary oxide systems and intimately packaged nanoparticles on the surface are widely recognized as not just an easy overlap of the properties of the individual components with the characteristics of the binary materials obtained.…”

This work concludes the synthesis of CeO-CuO nanocomposite by one-pot preparation method using three different molar ratios. The resulted nanocomposite was characterized using UV-Vis, XRD, SEM, EDX and TEM and the results show that this nanocomposite was found as spherical-like nanoparticles with high purity and the average particle size is in the range of 10-20 nm.. Furthermore, this nanocomposite was used in the solar cell application as photo anode and the results showed that the efficiency increase with increase of (x) content in the (CuO)x–(CeO2)1-x.

“…Environment deterioration, including water contamination, is becoming more and more alarming as the energy consumed by the population and its industrial activities increase [1,2]. The photocatalytic assistance of nano-semiconductors attracts a lot of interest in pollutant degradation and removal from water and hydrogen energy production because of their e ciency, cost-effectiveness, and environmental friendliness [3,4].…”

The direct Z-scheme GdFeO3/g-C3N4 photocatalysts used without any mediators were obtained using an ultrasonic synthesis approach. The composites’ structures, elemental composition and morphologies, as well as optical, electrochemical and catalytic properties, were thoroughly analyzed. GdFeO3/g-C3N4-3:7 composite exhibited an excellent enhanced light-harvesting ability and low recombination rate, which manifested into an outstanding visible-light driven activity, 7.7 and 2.3 times more than of stand-alone g-C3N4 and GdFeO3, respectively. A mechanism responsible for the photocatalytic property enhancement was proposed. The stability and reusability of the GdFeO3/g-C3N4 composites make them excellent materials for practical applications related to the removal of organic pollutants from the wastewater.
