An electrochemical study of the nickel hydroxide-gold modified electrode employing the surface resistance technique
(Elsevier Science Sa, 2016-08)
Simultaneous cyclic voltammetry (CV) and surface resistance (SR) measurements were employed to study the electrochemical behaviour of the nickel hydroxide-gold modified electrode. To this end, firstly, gold film electrodes ...
Surface resistance change during nickel hydroxide phase transformations
(Elsevier Science Sa, 2017-05)
Nickel hydroxide undergoes profound structural transformations under prolonged potential cycling in alkaline solutions. In this work, gold film electrodes modified with different nickel hydroxide coverages were subjected ...
The charge transport process at gold electrodes modified by thick nickel hydroxide films. A study employing rotating disc electrode voltammetry in the presence of the Fe(CN)6 3 −/4 − redox couple
(Elsevier Science Sa, 2016-12)
Rotating disc electrode voltammetry (RDEV) was employed to study the transport properties of nickel hydroxide films electrochemically deposited on gold in the presence of the Fe(CN)6 3 −/4 − redox couple. Gold electrodes ...
