Simultaneous and Selective Electrochemical Determination of Catechol and Hydroquinone on A Nickel Oxide (NiO) Reduced Graphene Oxide (rGO) Doped Multiwalled Carbon Nanotube (fMWCNT) Modified Platinum Electrode

Sensitive rGO/MOF based electrochemical sensor for penta-chlorophenol detection: a novel artificial neural network (ANN) application

“…Moreover, rGO has benefits over graphene in the electron transfer rate, π-electron distribution, biocompatibility, density at active sites, and adsorption capacity. 14 Besides, to predict and simulate the performance of the sensors quantitatively, various numerical simulations have been used, such as principal component analysis (PCA), multiple linear regression, partial least squares, and artificial neural network (ANN). Among these approaches, ANNs are considered efficient in quantitative prediction of (i) undetectable low concentrations that are too close to the sensor's detection limit (LOD) and (ii) the relationship between these concentrations and their exact responses.…”

“…On the contrary, electrochemical techniques provide sensitive platforms for determining phenolic compounds in a simple, quick, affordable, and selective manner. [12][13][14] Electrochemical sensors have been widely used in the development of sensitive and selective instruments due to their high specific recognition, adsorption capacity for analytes, and chemical stability. Thus, electrochemical sensors have become a hot research topic as the nanotechnology and material science have advanced.…”

Fabrication of CeO2/GCE for Electrochemical Sensing of Hydroquinone

“…In 2019, Ahmad et al [ 21 ] also reported the fabrication of an HQ and catechol sensor using SnO 2 as the electrode material. In another work, Meskher et al fabricated NiO/rGO/f-MWCNTs on a platinum (Pt) electrode for the determination of HQ and catechol simultaneously [ 26 ]. This indicated that electrode materials have a significant role in the development of electrochemical sensors [ 1 ].…”

A Novel Pentachlorophenol Electrochemical Sensor Based on Nickel-Cobalt Layered Double Hydroxide Doped with Reduced Graphene Oxide Composite

“…[27][28][29] Still, NiCo-LDH may suffer from redox kinetics, which is limited by the mass diffusion rate resulting in poor conductivity due to the high mass loading capacity. 30 Therefore, the integration of carbonbased nanomaterials such as carbon nanotubes (CNTs), 31 graphene oxide (GO), 32 and reduced graphene oxide (rGO) [33][34][35] can be an appropriate solution to this problem. Hence, rGO offers superb features such as high conductivity, strong stability, and the presence of defective sites which are chemically active, making it the perfect candidate for improving the NiCo-LDH loading capacity and further boosting the electrochemical performance by accelerating the electron transfer rate.…”
