Electrochemical Impedance Spectroscopic Analysis of ZnS Nanorod Fabricated Using Butterfly Wings as Biotemplate

Abstract

This article describes the growth of zinc sulfide (ZnS) nanorod on glass/aluminum foil by employing butterfly wings as biotemplate. Upon calcinating (at 400°C), the butterfly wings soaked in ZnS nanoparticle suspension, with uniform cage-like nanostructures in nanodimensions, were found on glass/aluminum surface. The transverse and longitudinal dimensions of the nanorods were evaluated from scanning electron microscopy micrographs as 132 and 159 nm, respectively. Purity of the ZnS nanorod found on the specimen was checked by recording XRD (28.877°, 48.038°, and 57.174°) and Fourier transform infrared spectrometer spectra (663.7 and 551.68 cm-1). Luminescence natures of the nanorods were examined using photoluminescence spectral studies. The characteristic emission peak is shown in the visible region with strong intensity, while the excitation peak is shown at 267 nm. Electrochemical impedance spectroscopic analysis of ZnS nanorod exhibits double-layer capacitance value (C dl = 6.7 nF), and the Bode plot explains the stability of ZnS nanorod under the influence of electrical field.

Visible LED‐Assisted Effective Charge Separation in Ruthenium‐Doped ZnS System for Efficient Photodegradation of Organic Dye

“…The peak around 467 nm corresponds to the stoichiometric vacancies or interstitial vacancies . The emission peak at 481 nm and 492 nm may be due to the recombination of shallow delocalized donor level to V Zn . The slight increase of emission intensity around 368 nm in case of Zn 0.995 Ru 0.005 S is may be due to the introduction of sulphur vacancy in ZnS crystal structure by low doping of Ru.…”

Biologically Assisted Construction of Advanced Electrode Materials for Electrochemical Energy Storage and Conversion

“…Different materials, including carbons, polymers, metals, oxides, sulfides, and selenides have been synthesized for electrochemical energy storage, electrocatalysis, and electrochem-ical detection applications. [80][81][82][83][84][85] As schematically depicted by Figure 8A, metallic materials were synthesized via electroless deposition on surface functionalized butterfly-wing followed by detemplation. Different samples, including Au, Pt, Ag, and Ni, with butterfly-wing architectures were fabricated as highperformance electrode materials.…”
