Electrochemical Preparation of Yttrium Hexacyanoferrate on Reduced Graphene Oxide and Its Application to Analgesic Drug Sensor

Abstract

Herein, we report a template free and surfactant less electrochemical approach for the preparation of flower‐like yttrium hexacyanoferrate (YHCF) particles on reduced graphene oxide (RGO) modified glassy carbon electrode (GCE). The morphology of YHCF particles has been controlled by varying the molar ratio of Y(NO3)2 and K3Fe(CN)6 for the first time. The surface morphology of as‐prepared RGO/YHCF composite was characterized using SEM, EDX, IR and XRD methods. The electrocatalytic activity of the RGO/YHCF composite modified GCE towards Paracetamol (PA) oxidation has been investigated by using cyclic voltammetry (CV) and linear sweep voltammetry (LSV). Besides, the practical feasibility of the fabricated modified GCE has been demonstrated through the determination of PA from commercially purchased Paracetamol tablets.

Dispersion of multi-walled carbon nanotubes in [BMIM]PF 6 for electrochemical sensing of acetaminophen

“…The calculated slope (52.2 mV) was close to the theoretical one (59 mV pH −1) for a classical Nernstian process with the participation of equal number of protons and electrons [51]. The similar result was obtained in the literature for ACOP detection for different modified electrodes described in the literature as MWCNT [52], Pd/graphene oxide [53], poly(4-vinylpyridine)/MWCNT [25], Fe3O4-poly(diallyldimethylammonium chloride-graphene/GCE [54] and ytrium hexacyanoferrate/reduced graphene oxide/GCE [55].…”

Recent developments in carbon nanomaterial sensors

“…A wide range of graphene sensors for drug detection have been reported, including sensors for pesticides, 195 cocaine, 196,197 analgesics, 198,199 dopamine receptor agonists, 200,201 antimigraine drugs 202,203 amongst others. [204][205][206][207][208][209] Two recently developed optical sensors for cocaine were based on aptamerbased fluorescence turn-on and turn-off mechanisms.…”

An electrochemical approach: Switching Structures of rare earth metal Praseodymium hexacyanoferrate and its application to sulfite sensor in Red Wine

“…Owing to these unique features, several attempts have been made to prepare different REMs including GdHCF [7], NdHCF [8], EuHCF [9], HoHCF [4], ErHCF [10], and YbHCF [11]. In our group, we have prepared several MHCFs such as DyHCF, NdHCF, YHCF, LuHCF and SmHCF [12][13][14][15][16] to fabricate modified electrodes that have great potential in electrochemical sensor applications. In a recent report, Cerium hexacyanoferrate (CeHCF) has been prepared and studied in detail [3].…”
