Synthesis of Ce-doped NiFe2O4 nanoparticles and their structural, optical, and magnetic properties

Effects of Lanthanum Substitution and Annealing on Structural, Morphologic, and Photocatalytic Properties of Nickel Ferrite

“…These sites have the capacity to host a total of 24 cations. Within this inverse spinel structure, an exclusive occupation of A-sites by Fe 3+ ions arises, whereas the B-site is shared by Ni 2+ and Fe 3+ ions, both demonstrating electron exchange at the octahedral site, highlighting their unique electrical and magnetic properties [5]. The superior characteristics of nickel ferrites, such as a low permittivity superparamagnetism and favorable optical band gap (Eg) values, make them suitable for high-frequency applications [2,[4][5][6].…”

“…The properties of Ni-La ferrite nanoparticles are intricately linked to the chosen synthesis method, which impacts both composition and microstructure [8]. Several synthesis methods are worth mentioning, including ball milling, sol-gel, solid-state reaction, spray pyrolysis, microemulsion, thermal pyrolysis, hydrothermal, solvothermal, citrate gel auto-combustion, self-propagating high-temperature synthesis, microwave, or chemical coprecipitation [1][2][3][4][5][6][7][8][9]. Sol-gel is arguably the most versatile method, as it requires less time and offers a reduced cost due to the low temperature requirement; it is highly reproducible, allowing for a good stoichiometry control that leads to a homogenous, single-phase final product under normal ambient conditions [1][2][3][4][5][6].…”

Impact of Rare Earth Element Cerium on Structural and Magnetic Characterization of Different Nanoferrites

“…Priyadharshini et al [21] synthesized Ce-doped NiFe 2 O 4 nanoparticles by chemical co-precipitation method. It was noted that the lattice parameters are altered by the substitution of Cerium-doped Nickel ferrite lattice.…”

Innovative Nanomaterial Properties and Applications in Chemistry, Physics, Medicine, or Environment

“…Developing innovative nanomaterials unlocks new opportunities in physics, chemistry, medicine, and environmental protection [ 1 , 2 , 3 , 4 , 5 , 6 ]. Controlling and designing nanomaterials with precise properties (size, morphology, porosity, chemical, mechanical, photocatalytic, and magnetic properties) became a highly explored research topic.…”

“…and carbon-based (carbon nanotubes, graphene, graphene oxides, etc.) nanomaterials are the most explored [ 3 , 4 , 5 , 6 , 7 , 8 , 9 , 10 ]. Nanoparticles’ properties make them appropriate applicants for technical applications in biosensors, humidity sensors, photocatalysis, magnets, drug delivery, magnetic refrigeration, magnetic liquids, photoluminescence, microwave absorbents, ceramic pigments, gas sensing, corrosion protection, water decontamination, antimicrobial agents, biomedicine, and catalysis [ 10 , 11 , 12 , 13 , 14 , 15 , 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 , 24 , 25 ].…”
