Effects of anions on the underpotential deposition behavior of Cu on polycrystalline Pt

Abstract

Effects of anions on underpotential deposition behavior of Cu at polycrystalline Pt has been investigated by cyclic voltammetry, chronoamperometry and electrochemical impedance spectroscopy techniques.

Review on Current Progress of MnO2‐Based Ternary Nanocomposites for Supercapacitor Applications

“…form an adsorbed coating on the gold or platinum electrode surface. [49] All the above-mentioned charge storing mechanisms often operates simultaneously, depending on the nature of electrode and electrolyte materials employed during the device fabrication. [50] Similarly, it has been observed that certain redox-active materials such as LiCoO 2 , MoO 2 , NiMoO 4 , etc.…”

“…Such behavior is observed when metal ions like ‐ Cu 2+ , Pb 2+ , Hg 2+ , etc. form an adsorbed coating on the gold or platinum electrode surface [49] . All the above‐mentioned charge storing mechanisms often operates simultaneously, depending on the nature of electrode and electrolyte materials employed during the device fabrication [50] …”

Green supercapacitors: review and perspectives on sustainable template-free synthesis of metal and metal oxide nanoparticles

“…Due to their excellent charge storage capacity, inherent exibility for exible electronic devices, large potential window between 1 and +1 V, simple synthesis process, and low cost, conductive polymers, such as polypyrrole and polyaniline, have been extensively researched for supercapacitor applications. 4,64,98 However, during the insertion/extraction process, conducting polymers experience both swelling and shrinkage, which reduce the mechanical stability of the electrodes, and consequently the cycling stability of supercapacitors. In addition to conducting polymers, many transition metal compounds with greater electrochemical stability than polymerbased materials and higher capacitance than carbon-based materials have been studied for supercapacitor applications.…”
