We demonstrate this strategy using a quaternary materials library containing Mo, Ag, Ti, and Ru fabricated by combinatorial magnetron sputtering on a 10 cm diameter wafer providing 342 measurement areas. Surprisingly, binary Mo−Ru-containing catalyst compositions with comparatively low Ru content exhibited the highest activity. Using the polymer/metal precursor-based spray technique, Ni foam electrodes were modified with the Mo−Ru hit compositions and evaluated in a model electrolyzer in membrane electrode assembly (MEA) configuration. The electrodes showed a very low overpotential of only 132 mV at a comparatively high current density of −2 A cm−2 and a 24 h electrolysis stability at −1 A cm−2 with no observable degradation after the initial electrode conditioning.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 5","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400631","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143530780","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Large amplitude ramped Fourier Transformed Alternating Current Voltammetry (FTacV), a technique in which a sinusoidal potential-time oscillation is overlaid onto a linear potential-time ramp, is known to provide access to higher order harmonic components that are largely devoid of non-Faradaic current. Initially, a theoretical study reveals that the use of very large amplitude sinusoidal oscillations reduces the apparent effects of thermodynamic dispersion; conversely, frequency can be varied to change the sensitivity of the measurement to kinetic dispersion. Subsequently, FTacV measurements are used to probe a highly thermodynamically dispersed surface-confined ferrocene derivative attached to a glassy carbon electrode, with amplitudes ranging from 25 to 300 mV and low frequency, which minimises the impact of kinetic dispersion. The results from the experimental study validate the theoretical predictions, demonstrating that we can vary the amplitude in FTacV experiments to tune in and out of thermodynamic dispersion.","PeriodicalId":142,"journal":{"name":"ChemElectroChem","volume":"12 4","pages":""},"PeriodicalIF":3.5,"publicationDate":"2025-01-31","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/celc.202400572","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143431772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"化学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study investigates the feasibility of using HEs with commercial cathodes and highlights their respective merits and challenges. The feasibility of infusing and forming HEs in commercial cathodes via PIPS within both micron-sized and nano-sized confined spaces is proved.

In this publication, we propose a millimolar concentration additive blend that shall promote homogeneous Zinc plating with suppressed dendrite formation and reduce the influence of water-splitting reactions. We use 5.5 mM sodium dodecyl benzene sulfonate (SDBS). SDBS adsorbs at the Zinc electrode and forms a protection layer that promotes homogenous crystallization. 4.5 mM Ethylenediamine-tetraacetate (EDTA) is meant to hinder water splitting. It reduces the activity of water at the Zinc surface. Both additives together exhibit a synergistic effect, resulting in higher performance compared to cells with either additive alone. We propose a handover of the Zinc ions between the EDTA in solution and the SDBS layer as a reason for this effect.

TM like nickel, cobalt, and iron have emerged as promising candidates due to their abundance, lower cost, and tunable electronic properties. These materials can achieve comparable or superior performance to PGMs for specific reactions, such as the Oxygen Evolution Reaction (OER) and Hydrogen Evolution Reaction (HER). CVD and ALD offer precise control over film thickness, composition, and uniformity, critical factors influencing the electrocatalytic performance. The ability to dope or alloy transition metal thin films further optimizes their catalytic properties for specific applications. This review covers key concepts related to hydrogen technology, electrocatalytic performance, and deposition processes.
