One-pot in situ synthesis of a CoFe₂O₄nanoparticle-reduced graphene oxide nanocomposite with high performance for levodopa sensing

Abstract

We demonstrate that a new nanocomposite of CoFe2O4-reduced graphene oxide can be used as an enhanced electrochemical sensing platform for levodopa.

Progress in Photocatalytic Degradation of Organic Wastewater by Graphene Binary Composites

“…Photocatalysis refers to the catalytic reaction of photocatalyst under the action of light, which can mineralize organic pollutants into simple inorganic substances such as CO 2 and H 2 O [14] . Hence, the photocatalytic action of graphene complexes can realize the catalytic degradation of organic pollutants using nontoxic solar energy resources, avoiding secondary pollution to the environment, and is an economical, simple, efficient and promising wastewater treatment method [15] . In this paper, the preparation and application of graphene binary photocatalytic complex are summarized.…”

Review. Electrochemical sensors used in the determination of L‐Dopa

“…Li et al 48 described a simple protocol to synthesize cobalt‐ferrite magnetic nanoparticle‐reduced graphene oxide nanocomposite (CoFe 2 O 4 /RGO) that was obtained by a chemical co‐precipitation technique. The outcomes exhibited that the CoFe 2 O 4 nanoparticles were successfully formed with particles sizes between 460 and 510 nm ranges and were attached on the RGO nanosheets.…”

“…The CoFe 2 O 4 /RGO/GCE exhibited a good stability, reproducibility, and acceptable repeatability. The CoFe 2 O 4 /RGO modified electrode was successfully applied in urine and tablet samples obtaining acceptable recoveries in the range of 97.8‐103.2% for the determination of L‐dopa 48 …”

Structural, Magnetic, and Dielectric Properties of Ultrafine Nickel-Substituted Cobalt Ferrite-Reduced Graphene Oxide Nanocomposites

“…GO with its ample number of oxygenated functional groups, regarded as a semimetal, has the ability to orient the dipoles, along a particular direction, which accounts for the polarization to take place. On the other hand, we selected ferrites as llers and among them cobalt ferrite stands dominant and remains to be a robust ferromagnetic material that performs its best role in the ourishing elds of data storage systems [8,9]. Incorporation of a similar dopant like nickel in it, nds a better pathway to elucidate the storage capability, because a number of active grains from cobalt and nickel along with Fe ions, contribute to the overall dielectric properties [5,10].…”
