Resumen
Carbon is a frequently used electrode material and an important additive in catalyst films. Its corrosion is often reported during electrocatalysis at high anodic potentials, especially in acidic electrolyte. Investigation of the carbon corrosion in alkaline environment is difficult due to the CO<sub>2</sub>/CO<sub>3</sub> <sup>2-</sup> equilibrium. We report the on-line determination of electrolysis products generated on Ni<sub>x</sub>B/C hybrid electrocatalysts in alkaline electrolyte at anodic potentials using differential electrochemical mass spectrometry (DEMS).

Resumen
Anion exchange membrane water electrolysis (AEMWE) is a well developed technology for the conversion of water into hydrogen and oxygen. AEMWE is still a developing technology. One of the major advantages of AEM water electrolysis is the replacement ofconventional noble metal electrocatalysts with low cost transition metal catalysts. In this study, we report characterization of NiCoOxmixed metallic oxides synthesized by the hydrolysis method as anodic electrocatalysts for AEMWE.

Developing highly conductive and durable support materials for Ir-based electrocatalysts in acidic oxygen evolution reactions (OER) is one of the challenges to overcoming corrosion conduction during the anodic process.

Green hydrogen is becoming a hot commodity in the light of escalating oil and gas prices and their uncertain future availability. Among various electrolysis technologies, PEM water electrolysis (WE) is favorable for its portability, modularity, and the ability to integrate with intermittent, renewable energy sources. However, the upscaling of PEMWE is not feasible yet due to the need for rare and expensive metals as electrocatalysts. Specifically, iridium oxide is used as state-of-the art anodic electrocatalyst.

Resumen
During water electrolysis, the hydrogen evolution reaction that generates hydrogen gas is unavoidably accompanied by the anodic reaction that generates oxygen via the oxygen evolution reaction (OER). However, under OER conditions, many electrocatalysts undergo structural degradation and can become amorphous. Lattice oxygen oxidation was proposed as one of the possible causes for amorphization of perovskite oxides. However, because lattice oxygen oxidation is notoriously challenging to probe in experiments, its unambiguous detection in oxide electrocatalysts has been elusive so far. Here, I wil

Resumen
Recently, nanostructured copper oxides formed via anodizing have been intensively researched due to their potential catalytic applications in emerging issues. The anodic Cu2O and CuO nanowires or nanoneedles are attractive photo- and electrocatalysts since they show wide array of desired electronic and morphological features, such as highly-developed surface area. In CO2 electrochemical reduction reaction (CO2RR) copper and copper-based nanostructures indicate unique adsorption properties to crucial reaction intermediates. Furthermore, anodized copper-based materials enable formation of C2+ hy

Resumen
The electrification of the petrochemical industry will greatly reduce greenhouse gas emissions in the manufacturing of commodity chemicals; however, electrification on a global scale is only achievable using earth-abundant materials for electrocatalysis in place of state-of-the-art catalysts made from precious metals. A promising catalyst that has been used for industrial hydrodesulfurization and electrocatalytic hydrogen evolution, nitrate reduction, carbon dioxide reduction, and oxygen evolution is Ni2P.

Resumen
The catalytic activity of Sr2PdO3, prepared through the sol-gel citrate-combustion method for the oxygen evolution reaction (OER) in a 0.1 M HClO4 solution, was investigated. The electrocatalytic activity of Sr2PdO3 toward OER was assessed via the anodic potentiodynamic polarization and electrochemical impedance spectroscopy (EIS). The glassy carbon modified Sr2PdO3 (GC/Sr2PdO3) electrode exhibited a higher electrocatalytic activity, by about 50 times, in comparison to the unmodified electrode. The order of the reaction was close to unity, which indicates that the adsorption of the hydroxyl gr

The field of electrochemical carbon dioxide reduction has developed rapidly during recent years. At the same time, the role of the anodic half-reaction has received considerably less attention. In this Perspective, we scrutinize the reports on the best-performing CO<sub>2</sub>&nbsp;electrolyzer cells from the past 5 years, to shed light on the role of the anodic oxygen evolution catalyst. We analyze how different cell architectures provide different local chemical environments at the anode surface, which in turn determines the pool of applicable anode catalysts.

AbstractThe efficient anion exchange membrane water electrolysis is challenging with low cell voltage and long‐term stability at large current density, due to the unstable anodic oxygen evolution reaction (OER). Fe‐based electrocatalysts are potential candidates for the anodic OER. In Fe‐based materials, iron oxides always show better stability in alkaline solution but lower OER activity. However, the catalysts in previous study are difficult to continuously and effectively activate iron oxides supported on carbon during electrocatalysis.

Abstract Chlorine, a chemical of significant importance, has been produced in chlor-alkali process utilizing dimensionally stable anodes (DSA) for an extended period. However, the inherent limitations of DSA have prompted the exploration of alternative electrocatalyst for chlorine evolution reaction (CER). In this study, we have focused on transition metal (TM) incorporated in the porphyrin center (TMP) as electrocatalyst toward anodic CER, which have been theoretically investigated based on quantum chemical density functional theory (DFT) method.

Resumen
Energy-efficient water electrolysis is one of the most promising techniques for generating green hydrogen as a carbon-free energy source. As a half-reaction of water splitting, the oxygen evolution reaction is kinetically sluggish, leading to large thermodynamic potential gaps compared to the hydrogen evolution reaction. In terms of cost-effective hydrogen generation, mitigating this overpotential is a challenging obstacle, but it remains a hurdle to overcome. It is necessary to advance energy-saving hydrogen production by substituting with an oxygen evolution reaction as a thermodynamically f
