Introduction to Znfe2o4 Nanoparticles

What is/are Znfe2o4 Nanoparticles?

Znfe2o4 Nanoparticles - In comparison with ZnFe2O4 nanoparticles(NPs) catalyst, the ZnFe2O4-rGO NCs can generate more hydroxyl radicals (•OH) via photoelectron chemical decomposition of H2O2. ^[1] The effects of polyvinyl pyrrolidone (PVP) as a capping agent on the structure, morphology, magnetic hysteresis (M–H) loop, optical and dielectric properties of ZnFe2O4 nanoparticles synthesized by a co-precipitation method were investigated. ^[2] Compared with Fe3O4 and MnFe2O4 nanoparticles, ZnFe2O4 nanoparticles exhibited a superior photothermal effect. ^[3] In this study, ZnFe2O4/CdS composites have been successfully synthesized from decorating CdS nanospheres with ZnFe2O4 nanoparticles by a facile method. ^[4] The results of TEM and XPS show that the ZnFe2O4 nanoparticles spread on the thin layers of Na-bentonite due to intercalation with Na-bentonite. ^[5] TEM images demonstrate that ZnFe2O4 nanoparticles are spherical in shape (9 ± 2 nm) and ZnFe2O4-TiO2 nanocomposite exhibits spherical-like morphology (11 ± 3 nm). ^[6] ZnFe2O4 nanoparticles (NPs) are homogeneously anchored on the rGO sheets. ^[7] ZnFe2O4 nanoparticles showed good photocatalytic activity under UV light irradiation. ^[8] Herein, ZnFe2O4 nanoparticles with different {001} and {111} facets exposed were successfully synthesized via a facile hydrothermal method. ^[9] The excellent microwave absorption performance of the ZnFe2O4@PPy nanocomposites is attributable to the synergistic effects of magnetic losses (ZnFe2O4 nanoparticles), dielectric losses (ZnFe2O4 and PPy) and interfacial relaxation losses at ZnFe2O4-PPy interfaces. ^[10] The as-prepared samples have been characterized by XRD, TEM, XPS and other detection methods, which demonstrate that ZnFe2O4 nanoparticles (NPs) with a diameter of 15 ∼ 50 nm were densely grown on the rGO substrates. ^[11] We concluded that replacing Zn2+ ions with Co2+ ions changes both the structural and magnetic properties of ZnFe2O4 nanoparticles. ^[12] The ZnFe2O4 nanoparticles (ZNF NPs) modified ZnO nanorods (NRs) have proven to be an effective strategy to enhance photoelectrochemical water splitting applications. ^[13] The influence of different Zn salts includes zinc nitrate, zinc sulfate, zinc chloride, zinc acetate on the crystal structure, surface morphologies, optical properties, magnetic properties, and photocatalytic activity of the ZnFe2O4 nanoparticles were systematically studied. ^[14] In ZnFe2O4 nanoparticles or bulk materials, the superexchange interaction between the (A) and [B] sites does not seem to favor magnetization at room temperature, and when measured below room temperature they show ferromagnetic behavior. ^[15] The covalent C-O-M linkage between ZnFe2O4 nanoparticles and C/RGO promotes charge transfer and enhances structural stability. ^[16] The surface engineering of ZnFe2O4 nanoparticles was performed by coating with chitosan using simple precipitation method. ^[17] Electro catalytic competency was exhibited by ZnFe2O4 nanoparticles modified screen printed electrode (SPE) for sertraline oxidation. ^[18] X-ray diffraction confirms the formation of the cubic spinel crystal structure of ZnFe2O4 nanoparticles with an average crystallite size of 20 nm. ^[19] The nanoparticles used for the tests are based on GaN thin layers grown on commercial ZnO and ZnFe2O4 nanoparticles. ^[20]

reduced graphene oxide

Spinel ferrite structured ZnFe2O4 nanoparticles anchored on reduced graphene oxide (rGO) sheets have been prepared via a facile hydrothermal method combined with a solvothermal approach. ^[1] In this work, a magnetically separable mesoporous composite of ZnFe2O4 nanoparticles (NPs) and reduced graphene oxide (rGO) was prepared through a simple and eco-friendly method with pure water as solvent and without the need for subsequent thermal treatment. ^[2] Herein, we demonstrated 5, 10, 15, 20-tetrakis (4-carboxylpheyl)-porphyrin modified magnetic ZnFe2O4 nanoparticles loaded on the surface of reduced graphene oxide (Por-ZnFe2O4/rGO), which exhibited intrinsic peroxidase-like activity and rapidly oxidized the peroxidase substrate 3, 3', 5, 5'-tetramethylbenzidine (TMB) into a blue product (OxTMB) distinguished by naked eyes. ^[3]

Magnetic Znfe2o4 Nanoparticles

A facile MALDI-TOF mass spectrometric platform for quantitative analysis of protein biomarkers was developed based on magnetic ZnFe2O4 nanoparticles and mass tagging signal amplification. ^[1] Magnetic ZnFe2O4 nanoparticles were stabilized using biomass derived cellulose to fabricate high performance cellulose based nanocomposites. ^[2] Herein, we demonstrated 5, 10, 15, 20-tetrakis (4-carboxylpheyl)-porphyrin modified magnetic ZnFe2O4 nanoparticles loaded on the surface of reduced graphene oxide (Por-ZnFe2O4/rGO), which exhibited intrinsic peroxidase-like activity and rapidly oxidized the peroxidase substrate 3, 3', 5, 5'-tetramethylbenzidine (TMB) into a blue product (OxTMB) distinguished by naked eyes. ^[3]

Doped Znfe2o4 Nanoparticles

The synthesized pure and Al-doped ZnFe2O4 nanoparticles were annealed at different temperatures such as 500, 600, 700 and 800 °C. ^[1] 2% Sm doped ZnFe2O4 nanoparticles easily removed 65% of dye within 1 hour duration. ^[2] Cu-doped ZnFe2O4 nanoparticles (Cu-ZFNPs) with spinel structure were synthesized by a facile hydrothermal route without using any surfactant. ^[3]

Numerou Znfe2o4 Nanoparticles

Novel ZnFe2O4 hollow spheres constructed by numerous ZnFe2O4 nanoparticles are successfully prepared via a simple one-step hydrothermal treatment and subsequent calcination, in which carbon sheets act as the template. ^[1] The as-prepared hybrid nanocomposites showed good dispersion of nanoparticles as the additive amounts of GO increasing and numerous ZnFe2O4 nanoparticles uniformly loaded on the crumpled surface of thinly flake-like NRGO were observed. ^[2]

Spinel Znfe2o4 Nanoparticles

Spinel ZnFe2O4 nanoparticles showed good adsorptive capacity and the maximum monolayer coverage (Q0) was determined as 46 mg/g of the adsorbent. ^[1] Spinel ZnFe2O4 nanoparticles (NPs) were successfully synthesized by a simple microwave irradiation method (MIM) using glycine as the fuel. ^[2]

Pure Znfe2o4 Nanoparticles

It has been affirmed by the surface characterization investigation that established nanocomposites acquired improved specific surface areas when correlated with the surface areas of both pure ZnFe2O4 nanoparticles (NPs) and pure g-C3N4 nanosheets. ^[1] The composite showed better photocatalytic activity than the pure ZnFe2O4 nanoparticles. ^[2]
