Gas diffusion electrode was used for providing better conditions in fuel cell systems for oxygen reduction reaction (ORR). Because the slow kinetics of the oxygen reduction reaction at the proton exchange membrane fuel cell cathode restricts fuel cell efficiency. To this end, researchers have used platinum-coated carbon. In the present study, due to the reduction of carbon corrosion, Zinc oxide...

A modest, efficient, and sensitive chemically modified electrode was fabricated for sensing curcumin (CRC) through an electrochemically polymerized titan yellow (TY) carbon paste (PTYMCPE) in phosphate buffer solution (pH 7.0). Cyclic voltammetry (CV) linear sweep (LSV) differential pulse (DPV) approaches were used CRC detection. PTYMCPE interaction with suggests that the exhibits admirable ele...

Abstract Electrochemical corrosion of lower-activity spent fuel simulants, SIMFUELs, has been investigated in support on-going analogous studies a real AGR nuclear electrode. Two electrode coupling methods have investigated, to study the sample 25 GWd/tU SIMFUEL pellet 20/25/Nb cladding replicate setup. Method-1 involves individual standalone electrodes, while Method-2 and within same For both ...

Here, we describe a strategy for preparing CdS/MoS2 heterostructures using initially electrodeposited MoSx on polycrystalline gold substrate. The excess sulfur intrinsic to the MoS3 surface was derivatized with Cd form spherical particles by judicious adjustment of medium pH and interfacial electrochemistry. progression this conversion monitored combination cyclic/linear sweep voltammetry coupl...

This study is conducted to explore the effective and stable electrode materials for electrochemical reduction of CO2. The different compositions (3 - 8%) CuO-supported CNT samples were prepared by a traditional sol-gel method, characterized TGA, SEM, TEM, FTIR XRD. characterization results confirmed uniform impregnation CuO on defects CNT's, which improved utilization meso microporous distribut...

Numerical simulations based on the time dependent backward implicit method are used to develop the theory of anodic stripping voltammetry carried out under hydrodynamic conditions using mercury thin film wall-jet electrodes. The peak shape is shown to be highly sensitive both to electrolyte flow rate and to the potential sweep rate. The simulations permit visualization of concentrations both in...

Hydrogen peroxide (H2O2) plays a pivotal role in various industrial applications [1]. It is an essential mediator in pharmaceutical, clinical, and environmental research. In addition, it is a byproduct of highly selective oxidases and an important contaminant in several industrial products and wastes [2]. Therefore, a reliable and economical method for the determination of H2O2 is of great sign...

We report a stripping voltammetric method for the detection of aqueous As(III) using Pt macroelectrode or nanoparticle-modified glassy carbon electrode (GCE) which, novelly, is based on underpotential deposition As atoms. The consists pre-concentration reductive step to accumulate ad-atoms onto Pt, followed by linear sweep voltammetry (LSV). It shown that peak improves response at low concentra...

Heterostructures have recently been used to generate stable photo-induced currents via photoelectrochemical (PEC) activity. However, the effect of electrolytes on charge-transfer kinetics and generation heterostructures are major challenges in PEC. The electrolyte synthesized photoelectrodes is demonstrated this study under various conditions using electrochemical impedance spectroscopy, linear...
