“…The relation between potential and current is an important characteristic in electrochemistry, describing electrocatalytic activities, − electrodeposition processes, , corrosion, , redox processes, capacitances, − cell performances, , and so forth. To characterize these electrochemical properties, one typically applies a time-dependent potential and measures the current or vice versa.…”

The intrinsic potential dependence of double-layer capacitances contributes to every cyclic voltammetry (CV) measurement. This study presents a dynamic transmission line model to describe the potential dependence of double layers in CV, exemplified and parameterized for a polished gold electrode. In detail, impedance spectra are measured under an incremental potential variation, from which a potential-dependent parameterization of the double layer in the form of constant phase elements in the frequency domain is derived. This parameterization is used to generate a dynamic potential-dependent transmission line network, in which the current response to potential variations is calculated on the basis of differential equations in the time domain. This approach adequately describes the impact of the potential on the double layer response of the gold electrode during CV. The presented model is discussed to represent the ion transport in the double layer directly by its physical interpretation as a dynamic transmission line, building an illustrative bridge between the physicochemical double-layer dynamics of real systems and the model world.

“…Ni-based alloys are widely used cathodes for the electrolysis of alkaline waters due to the relatively high catalytic activity of Ni, and the synergism in the catalytic behavior of various components in the metal alloy. Alloys such as NiCo [35][36][37][38][39][40][41], NiFe [42][43][44][45][46], NiMo [43,[47][48][49][50][51][52][53][54][55][56][57][58][59], NiW [47,60,61], NiCu [62,63], NiAl [6,[64][65][66][67][68], NiZn [69][70][71][72][73], NiMoFe [56,[74][75][76][77] were used by means of different methods. Materials based on nickel and molybdenum attract ever growing attention because of their activity for HER and sufficient corrosion resistance in...…”

The review paper accumulates the latest information on the analysis of catalyst synthesis for the electrolysis of water in alkaline and partially in acidic media. Literature data on the production of electro-catalysts based on noble, refractory, transition and pure metals, as well as metals doped with molybdenum, phosphorus, and other elements, are presented. Given the different methods of synthesis of electro-catalyst, the advantage of the electrochemical method is emphasized as easy, accessible method enabling to regulate the composition of synthesized electrodes by changing the content of an electrolyte and the conditions of electrolysis, controlling the properties of synthesized materials.
