Special Issue Information

Dear Colleagues,

The increasing demand for clean energy has caused a disruption in the need and supply balance within the energy sector. This has driven an extensive search for alternative energy sources, more efficient methods of energy production, and efficient means of storing the produced energy. The generation of hydrogen, oxygen and syngas through electrocatalytic processes could solve this challenge, as it offers a sustainable way to store green energy. The Special Issue, titled "Electrocatalysts for the Production of Hydrogen, Oxygen and Syngas", aims to provide a comprehensive overview of the current state of the art in the field of electrocatalysis for hydrogen, oxygen and syngas production. It should also help in addressing the energy storage challenges.

The Special Issue invites submissions of original research articles, reviews and perspectives covering various aspects of electrocatalysts for the production of hydrogen, oxygen and syngas. Topics of interest include, but are not limited to, the design, synthesis and characterisation of electrocatalysts; mechanisms of electrocatalytic reactions; the development of new electrocatalytic processes; and the application of electrocatalysts in fuel cells, electrolysers and syngas reactors. Additionally, the issue welcomes contributions that highlight the challenges and opportunities associated with the commercialisation of electrocatalytic processes and technologies.

In conclusion, this Special Issue aims to provide a comprehensive and up-to-date overview of the field of electrocatalysis for hydrogen and oxygen production, as well as the production of syngas, and to foster new insights and ideas for future research and development in this important and rapidly advancing area of research and science.

The hydrogen evolution reaction (HER) holds pivotal significance in electrochemical energy conversion. In this study, we present essential HER kinetic parameters encompassing nine metals (Ag, Au, Co, Cr, Fe, Ni, Pt, W, and Zn) evaluated within seven distinct electrolytes (0.1 mol dm−3 HClO4, 0.1 mol dm−3 HCl, 0.5 mol dm−3 NaCl, 1 mol dm−3 KH2PO4, 0.1 mol dm−3 KOH, 0.1 mol dm−3 LiOH, and 1 mol dm−3 KOH). Through careful measures to restrain oxide formation, HER activity was measured on clean electrodes, while the assessment of HER activity on oxidatively treated metals was also performed. By correlating HER exchange current densities with calculated hydrogen binding energies, we show that the shape of HER volcano curves is largely preserved in studied electrolytes, at least around their apexes. Additionally, depending on the metal–electrolyte combination, the presence of surface oxide can have both positive and negative effects on HER kinetics. Finally, we collated HER kinetic data for bulk surfaces from diverse literature sources, offering a comprehensive overview of the kinetic parameters governing hydrogen evolution across distinct electrolytic environments. These insights have practical significance, guiding the development of new catalytic materials for different water electrolysis technologies, optimizing electrolyte formulations for boosting HER, and enhancing energy efficiency and catalytic performance through catalyst–electrolyte synergies.
