Dependence of Catalytic Activity of Nanocrystalline Nickel Ferrite on Its Structural, Morphological, Optical, and Magnetic Properties in Aerobic Oxidation of Benzyl Alcohol

The structural, magnetic, and optical properties of Ni–Mg–Zn ferrite prepared with different complexing agents via sol–gel method

“…The photoluminescence spectroscopy is an important technique for studying optical properties and obtaining information about band gap defect states of spinel structure in semiconducting materials [54]. In spinel structure ferrite, due to cation disorder, there are many defects, which can be regarded as electron or hole traps [55].…”

NiFe2O4nanoparticles: an efficient and reusable catalyst for the selective oxidation of benzyl alcohol to benzaldehyde under mild conditions

“…The conversion of benzyl alcohol reached a maximum of 77% with 100% selectivity. 36 Sadri et al reported the use of the magnetically separable nano-CoFe 2 O 4 catalyst for oxidation of primary and secondary benzylic and aliphatic alcohols to produce the corresponding carbonyl products in water with oxone as the oxidizing agent at room temperature. 37 Zhu et al reported the use of CuFe 2 O 4 as a catalyst for the oxidation of benzyl alcohol in the presence of TEMPO in water at 100 °C for 24 h using O 2 as the oxidant.…”

NiFe2O4@B,N,F-tridoped CeO2 (NFTDNC): a mesoporous nanocatalyst in the synthesis of pyrazolopyranopyrimidine and 1H-pyrazolo[1,2-b]phthalazine-5,10-dione derivatives and as an adsorbent

“…56 The band at 652 nm was the characteristic band of the spinel nanoparticles of nickel ferrite. 30 The configuration along with the chemical state of surface elements present in the synthesized NFTDNC nanostructures was ascertained via X-ray photoelectron spectroscopy (XPS) analysis. Fig.…”

“…Spinel ferrites, a class of bimetallic magnetic nanomaterials exhibit an extensive variety of applications in gas sensing, drug delivery, high density, ferrofluids, microwave devices, electro-communication and various other fields. [28][29][30] Nickel ferrite, a unique magnetic spinel material has small hysteresis, tunable bandgap (∼1.7 eV) resulting in efficient solar light utilization, chemical durability and high magnetic separation. 31,32 The domino multicomponent reaction (MCR) inevitably engrossed the organic chemists as it not only encompasses the merits of multicomponent reactions but also addresses their demerits such as more wastage and lower yield.…”
