“…209,210 Ni-based electrocatalysts are attractive candidates for the GOR due to their relatively high electrocatalytic activity, toxicity resistance, and long-term stability in alkaline solutions. 208,[210][211][212][213][214][215] Baranova and Houache studied many Nibased electrode materials for the GOR in recent years. In 2018, they investigated the GOR on polycrystalline Ni electrodes in alkaline media after sinusoidal-wave treatment.…”

“…Even today, world energy demand is supplied mainly by petroleum derivatives. Thus, in order to face the predictable depletion of such resources and to reduce the impact caused by the burning of these fuels, the use of renewable sources is essential. − As a consequence, a great deal of work has been directed to investigate alcohol electro-oxidation reactions for various applications such as (i) energy conversion devices (e.g., fuel cells); − (ii) processes involving electrosynthesis of organic compounds; , and (iii) electrolyzers, aiming at the production of hydrogen with cogeneration of high-value chemicals (mainly in the case of glycerol). − …”

This study describes a systematic investigation of the electrocatalytic activity of poly [Ni(salen)] films, as catalysts for the electrooxidation of Cn alcohols (Cn = methanol, ethanol, and glycerol) in alkaline medium. The [Ni(salen)] complex was electropolymerized on a glassy carbon surface and electrochemically activated in NaOH solution by cyclic voltammetry. X-ray diffraction, transmission electron microscopy, and X-ray photoelectron spectroscopy results indicate that during the activation step the polymeric film hydrolyzes, leading to the formation of β-Ni(OH) 2 spherical nanoparticles, with an average size of 2.4 ± 0.5 nm, encapsulated with the poly[Ni(salen)] film. Electrochemical results obtained together with the in situ Fourier transform infrared spectroscopy confirm that the electrooxidation of methanol, ethanol, and glycerol occurs by involving a cycling oxidation of β-Ni(OH) 2 with the formation of β-NiOOH species, followed by the charge transfer to the alcohols, which regenerates β-Ni(OH) 2 . Analyses of the oxidation products at low potentials indicate that the major product obtained during the oxidation of methanol and glycerol is the formate, while the oxidation of ethanol leads to the formation of acetate. On the other hand, at high potentials (E = 0.6 V), there is evidence that the oxidation of Cn alcohols leads to carbonate ions as an important product.

“…Nowadays, preparing the environmental‐friendly energy storage materials aroused great attention [1, 2], due to the rapid development of modern electronic industry causing serious environmental pollution problems. So people are exploring ways to make hydrogen and oxygen by electrolysis H 2 O or small molecules, such as glucose [3], urea [4], methanol [5], ethanol [6], ammonia borane [7] and glycerol [8]. In addition, the recycling of waste liquid as hydrogen production resources conforms to the concept of green chemistry and has a very good development prospect.…”

The Ni(OH) 2 /NiOOH nanoparticles (NPs) electrodeposited on a glassy carbon electrode (GCE) in Ni(NO 3) 2 and NH 3 •H 2 O aqueous solution for the electrode materials. Then the nickel hydroxide/oxyhydroxide acetate was formed in acetate solution. The effects of deposition conditions such as the concentration of Ni(NO 3) 2 solution, the number of sedimentary cycles, the concentration of acetate in the soaking liquid and the soaking time are discussed in detail. The electrochemical properties of the material have been investigated by cyclic voltammetry, Tafel curve, EIS and amperometric it curve techniques. The result displays excellent electrocatalytic activity towards the electrocatalytic oxidation of urea in alkaline solution. Furthermore, the modified electrode for oxidation reaction has the advantages of simple preparation, good electrochemical properties and stabilisation.
