Fabrication of Nanostructured Ni and Ni-Pd electrodes for wateralkaline electrolyzer
2016
In the last years many attention has been dedicated to the increase of performance of Nichel based electrodes to use in water-alkaline electrolyzes. In our preliminary work we have shown that alkaline electrolyzer made with Ni nanowires covered with IrO2 (side oxygen evolution) nanoparticles and a Ni sheet (side hydrogen evolution) have very good and stable performance also at room temperature [1]. In this work, to obtain a complete nanostructured electrolyzer, the attention was focused on the fabrication of electrodes for hydrogen evolution. In particular, by metal displacement deposition we have grown on Ni nanowires electrodes, nanoparticles of Pd with the aim to enhance the electrocatal…

Optimization of Electrodeposited Nickel-Zinc Alloys for Alkaline Electrolyzer with Nanostructured Electrodes
It is common opinion that hydrogen will become increasingly important over time. However, many research efforts still need to be made to develop efficient, low-cost and carbon-free hydrogen production. In this context, electrolysers will play a key role, but it is necessary to develop efficient and low-cost electrode/electrocatalyst materials. In this work, Nickel-Zinc alloy electrodes with nanowires morphology were investigated as cathode for alkaline electrolyzer. Electrodes were obtained by the simple method of template electrosynthesis that is also inexpensive and scalable. Nanostructured electrodes were analysed by morphological and chemical analyses. The nanowires composition is depen…
Nanostructured Lead Electrodes with Reduced Graphene Oxide for High-Performance Lead–Acid Batteries
2022
Nanostructured Pb electrodes consisting of nanowire arrays were obtained by electrodeposition, to be used as negative electrodes for lead–acid batteries. Reduced graphene oxide was added to improve their performances. This was achieved via the electrochemical reduction of graphene oxide directly on the surface of nanowire arrays. The electrodes with and without reduced graphene oxide were tested in a 5 M sulfuric acid solution using a commercial pasted positive plate and an absorbed glass mat separator in a zero-gap configuration. The electrodes were tested in deep cycling conditions with a very low cut-off potential. Charge–discharge tests were performed at 5C. The electrode wi…
