Abstract For the advancement of electrochemical energy conversion and storage technologies, bifunctional electrocatalysts are crucial for efficiently driving both oxygen evolution (OER) reduction reactions (ORR). Cobalt‐based spinel oxides a class promising electrocatalysts. However their low electrical conductivity stability may hinder further improvement. A novel composite material composed NiCo 2 O 4 nanoparticles integrated with emerging two dimensional MXene nanosheets (NiCo /MXene) was...
A series of cobalt ferrite samples were synthesized from a metal nitrate solution at constant pH between 9 and 12 by the controlled co-precipitation method without any surfactant.
The oxygen evolution reaction (OER) and the hydrogen occurred at anode cathode, which depends on electronic structure, morphology, electrochemically active surface area, charge-transfer resistance of electrocatalyst. Transition metals like cobalt, nickel, iron have better OER reduction activities. At same time, transition-metal oxide/carbon hybrid has several applications in electrochemical energy conversion reactions. rich catalytic site transition excellent conductivity carbon material...
TiO 2 /RGO nanocomposites were synthesised via a simple one-pot hydrothermal method and used as modifier in carbon paste electrode for the sensitive determination of serotonin.
Metal oxide/reduced graphene oxide (MO/RGO, MO = NiO, Co 3 O 4, and SnO 2 ) nanocomposites were synthesized by a cost-effective hydrothermal method. The structural, thermal, morphological characteristics of composites investigated using PXRD, FT-IR, TGA, Raman, SEM, HR-TEM. Modified carbon paste electrochemical sensors based on NiO/RGO, 4 /RGO, /RGO developed compared for the effective detection Epinephrine (EPN), Serotonin (SER), Tyrosine (TYR). performance NiO/RGO/CPE sensor was superior...
A novel electrochemical sensor for dopamine (DA) in the presence of serotonin (ST) was fabricated by modifying a glassy carbon electrode with BaMnO3 and super P black. The modifier, synthesized co-precipitation method subsequent calcination. formation pure crystalline form ensured during synthesis verified characterization techniques such as powder X-ray diffraction, infrared spectroscopy, Raman, thermogravimetry, Ultraviolet–visible scanning electron microscopy, transmission microscopy...
This paper demonstrates a highly sensitive, selective, biocompatible and cost-effective method for the simultaneous determination of Epinephrine (EPN), Uric acid (UA) Tyrosine (TYR). Superior electrochemical performance was achieved using ZnO/RGO/CPE modified electrodes compared to individual components, graphene oxide (GO) ZnO electrodes. The activity fabricated sensor is examined through cyclic voltammetry (CV), differential pulse (DPV) chronoamperometry (CA). A sharp increase in anodic...
Microscopic dissociation constants of 3-hydroxy-alpha-(methylamino)methyl-benzenemethanol have been calculated from the titration spectrophotomeric data (c = 3.8 x 10(-4) M. Ionic strength 0.16; buffer system: H3BO3/KOH) by application a spectral deconvolution method. The results found (pKa 9.48; pKb 9.71; pKc 10.12 and pKd 9.88) are in good concordance with those obtained conventional regression linear method 9.45; 9.77; 10.14 9.81).
