Enhanced magneto-optical and photo-catalytic properties of transition metal cobalt (Co2+ ions) doped spinel MgFe2O4 ferrite nanocomposites

Magnetic clustering of Ni2+ ions in metal-ceramic nanocomposites obtained from Ni-exchanged zeolite precursors

“…In the last decade, the scientific interest towards magnetic nanostructured / nanocomposite materials has steadily increased owing to their functional properties associated with widespread applications ranging from electronics [1], magneto-optics and photocatalysis [2][3][4][5] to supercapacitors [6,7], hyperthermia [8], drug delivery [9,10], water remediation [11], energy harvesting [12]. Oxides of transition metals / rare earths have received particular attention because of the concurrence of magnetic effects and semiconducting-like properties [3,12,13] Magnetic metal-ceramic nanocomposites, consisting of a dispersion of Fe 0 , Co 0 , or Ni 0 nanoparticles into a prevailingly amorphous silica and alumina ceramic matrix, are an important sub-class of nanomaterials whose fields of application are typically associated with their porous structure, which makes them particularly suitable for use in environmental protection [14][15][16][17][18][19][20][21][22], catalysis [23][24][25][26][27][28] and biomedicine [29][30][31][32][33].…”

Frequency Dependence of Dielectric, Conductivity, Impedance and Electrical Modulus Properties of La3+ Substituted in Cobalt- Magnesium Ferrites

“…These slight decrease in crystallite size with the substitution of lanthanum ions in cobalt-magnesium ferrite results in increase in the surface area. This is associated with nucleation and particle growth (Godlyn Abraham et al, 2018). Also, it is known that, the particle growth depends on the grain boundaries, mobility, grain growth etc.…”

Construction of magnetic MgFe2O4/CdS/MoS2 ternary nanocomposite supported on NaY zeolite and highly efficient sonocatalytic degradation of organic pollutants

“…31 ) illustrate excellent supermagnetic features. For this reason, they can be utilized in various elds such as catalysis, [31][32][33] adsorption, [34][35][36] sensor, 37 drug delivery, 38 etc. Besides, coupling the MoS 2 /CdS with the MgFe 2 O 4 purveys a promising heterojunction system for improving the catalytic activity and recycling via using a simple external magnetic eld.…”
