Synthesis of nickel-sphere coated Ni-Mn layer for efficient electrochemical detection of urea

Scientific Reports, Journal Year: 2024, Volume and Issue: 14(1)

Published: June 27, 2024

Abstract Using a trustworthy electrochemical sensor in the detection of urea real blood samples received great attention these days. A thin layer nickel-coated nickel-manganese (Ni@NiMn) is electrodeposited on glassy carbon electrode (GC) (Ni@NiMn/GC) surface and used to construct for detection. Whereas, electrodeposition considered as strong technique controllable synthesis nanoparticles. Thus, X-ray diffraction (XRD), atomic force microscope (AFM), scanning electron (SEM) techniques were characterize produced electrode. AFM SEM pictures revealed additional details about morphology, which homogenous smooth coating. Furthermore, research was carried out alkaline medium utilizing various methods, including cyclic voltammetry (CV), chronoamperometry (CA), impedance spectroscopy (EIS). The investigations showed that had good performance, high stability effective charge transfer capabilities. structural, morphological, characteristics Ni@NiMn/GC electrodes well understood using analytical techniques. limit (LOD) equal 0.0187 µM linear range 1.0–10 mM urea. examine efficiency prepared sensor. Otherwise, anti-interfering ability modified catalyst examined toward interfering species.

Abstract The electrochemical effect of isotope (EEI) water is introduced in the Zn‐ion batteries (ZIBs) electrolyte to deal with challenge severe side reactions and massive gas production. Due low diffusion strong coordination ions D 2 O, possibility decreased, resulting a broader electrochemically stable potential window, less pH change, zinc hydroxide sulfate (ZHS) generation during cycling. Moreover, we demonstrate that O eliminates different ZHS phases generated by change bound cycling because consistently local ion molecule concentration, interface between electrode electrolyte. full cells O‐based demonstrated more performance which displayed ∼100 % reversible efficiencies after 1,000 cycles wide voltage window 0.8–2.0 V 3,000 normal 0.8–1.9 at current density A g −1 .
