“…In the vast scenario concerning both fuels and energy conversion devices, electrochemical systems play a crucial role for hydrogen production and energy accumulation (primary and secondary cells and supercapacitors) as well as electricity production by means of fuel cells [ 3 , 4 ]. In particular, hydrogen obtained from the electrolysis of water is proposed as an alternative to fossil fuels in many applications [ 5 , 6 ]. There are several electrolyzer technologies (Alkaline [ 7 , 8 , 9 ], Proton Exchange Membrane (PEMEL) [ 10 , 11 , 12 ], anion exchange membrane (AEM) [ 13 , 14 , 15 , 16 ] and Solid Oxide Electrolyzer [ 17 , 18 , 19 ]) with a different degree of technological and commercial maturity.…”

To realize the benefits of a hydrogen economy, hydrogen must be produced cleanly, efficiently and affordably from renewable resources and, preferentially, close to the end-users. The goal is a sustainable cycle of hydrogen production and use: in the first stage of the cycle, hydrogen is produced from renewable resources and then used to feed a fuel cell. This cycle produces no pollution and no greenhouse gases. In this context, the development of electrolyzers producing high-purity hydrogen with a high efficiency and low cost is of great importance. Electrode materials play a fundamental role in influencing electrolyzer performances; consequently, in recent years considerable efforts have been made to obtain highly efficient and inexpensive catalyst materials. To reach both goals, we have developed electrodes based on Pd–Co alloys to be potentially used in the PEMEL electrolyzer. In fact, the Pd–Co alloy is a valid alternative to Pt for hydrogen evolution. The alloys were electrodeposited using two different types of support: carbon paper, to fabricate a porous structure, and anodic alumina membrane, to obtain regular arrays of nanowires. The goal was to obtain electrodes with very large active surface areas and a small amount of material. The research demonstrates that the electrochemical method is an ideal technique to obtain materials with good performances for the hydrogen evolution reaction. The Pd–Co alloy composition can be controlled by adjusting electrodeposition parameters (bath composition, current density and deposition time). The main results concerning the fabrication process and the characterization are presented and the performance in acid conditions is discussed.

Amnio acids are essential for body life, and thus, introducing novel simples/sensitive techniques/catalyst for detecting their low levels, especially in real samples and mixtures, is a great issue in analytical/bioanalytical chemistry. Thus, NiO nanoparticles were synthesized and used for the modification of a carbon paste electrode (CPE) for the square wave voltammetric (SqW) determination of tyrosine (Tyr) in the presence of tryptophan (Tryp), phenylalanine (PhA), and cysteine (Cis) amino acids (AA), all having the À CH 2 À CH(NH 2 )À COOH functional group. The calibration sensitivity was increased in interfering AA species which caused the decreased detection (for example, detection limit (DL) 1.32 μM to 0.88 μM Tyr) and quantification limits. For different concentrations of interfering AA species, the linear range (LR) was decreased that was more intense with an increase in AA amount. For example, the LR of 5-1800 μM Tyr in the absence of other AA species was changed to 80-800, 90-850, and 70 À 1000 μM Tyr in the presence of 20 mM Tyr, Csy, and PhA, respectively. A g-value of 0.487 < g 0.05,6,5 = 0.5875 confirmed the long-term stability of the electrode for 4 months. The electrode showed good selectivity towards Tyr in the presence of some amino acids and inorganic salts. Recovery experiments also confirmed the good capability of the electrode in Tyr quantification in a complex matrix such as six human serums used.
