Summary: Zn-doped cobalt perovskites Co1-xZn1.5xFeO3 nanoparticles were synthesized using auto-combustion sol-gel approach. The effects of Zn doping on structural, morphological, dielectric, electrochemical, and photocatalytic properties were investigated. Zn doping significantly influenced the dielectric properties, AC conductivity, specific capacitance, and band gap energy of Co1-xZn1.5xFeO3. The photocatalytic activity of Co1-xZn1.5xFeO3, enhanced by Zn doping, showed promise for applications such as dye degradation under solar light irradiation.

Summary: Copper and dysprosium doped NiFe2O4 magnetic nanomaterials were prepared and investigated for the photodegradation of methylene blue pollutant, electrocatalytic water splitting, and antibacterial activities. The results showed that the doping of copper and dysprosium can increase the saturation magnetization and decrease the optical band gap, leading to enhanced photocatalytic degradation efficiency and excellent electrocatalytic properties. The produced magnetic nanomaterials also exhibited significant antibacterial activity against gram-positive bacteria.

Summary: Multi-metal spinel ferrite nanocrystals of Ni0.3Cu0.3Zn0.4Fe1.4Cr0.6O4 were synthesized using sol-gel auto-combustion route. The structural, magnetic, and dielectric properties of the nanocrystals were affected by calcination temperature. The prepared nanocrystals exhibited different crystallite sizes, lattice strains, dislocation densities, saturation magnetizations, retentivities, coercivities, magnetic anisotropies, dielectric constants, dielectric losses, conductivity values, and impedance values at low-frequency range. These nanocrystals have potential applications in capacitors, recording systems, high-frequency devices, and multilayer chip inductors.

Summary: This paper reports a solution auto-combustion (AC) process for the rapid synthesis of Fe3O4 nanoparticles derived from the sol-gel (SG) process. By using citric acid (CA) and tartaric acid (TA) as gelling agents in the SG process, citric acid acts as a fuel that combusts the gel and yields highly magnetic crystalline Fe3O4 nanoparticles in one step. In contrast, different concentrations of citric acid and any concentrations of tartaric acid do not induce combustion and only result in amorphous iron oxides. Upon annealing, the CA and TA derived iron oxide samples transform into crystalline alpha-Fe2O3 particles. Photocatalytic studies show that the synthesized Fe3O4 nanoparticles exhibit higher photocatalytic efficiency and stability under simulated solar light irradiation.
