Synthesis of Nickel Oxide Nano Material by Electrodeposition for Electrochemical Capacitive Analysis

Electrodeposition techniques is used for the deposition of nickel oxide thin film electrodes. In the present work, we report electrodeposition of nickel oxide thin film on the conducting stainless steel (SS) substrates for the application of electrochemical supercapacitor. X-ray diffraction confirms simple cubic crystal structure with polycrystalline nature of the deposited NiO sample that exhibits hydrophilic nature confirmed from the wettability study. The Scanning Electron Microscope (SEM) observed dense with cracky morphology. UV spectrum exhibits 3.55eV band gap of samples. The capacitive characteristics of the deposited thin film are investigated in 1M KOH electrolyte using cyclic voltammetry (CV). The supercapacitive properties of NiO are strongly affected by the scan rate. The maximum specific capacitance obtained is 162 F/g at 2 mV/s scan rate.

A Electrical and Optical Characteristics of Stannous Doped Nickel Oxide Thin Film Formed by Spray Pyrolysis Technique

Stannous slight film doped nickel oxide arranged on a glass substrate at 360 ° C with a splash pyrolysis strategy. Nio: Sn films framed on various proportions, for example, 0.1 M molarity: 0.01M and 0.lM: 0.03M. The movies were discovered uniform and follower to the substrate. its thickness was estimated utilizing a miniaturized scale balance technique. the electrical obstruction is estimated by a PC controlled Keithley electrometer and ingestion and vitality band hole determined for various wavelengths utilizing a spectrophotometer Elico cosmetics. high straightforwardness (above 80%) in the obvious locale is accomplished and profoundly execute Nio films acquired when doped with Stannous.
