Special Issue Information
Dear Colleagues,
This Special Issue, titled “Recent Progress on Electrocatalytic Hydrogen Evolution Reaction”, pertains to the hydrogen evolution reaction (HER), which is a cathodic reduction process that plays a crucial role in clean energy conversion. It is widely recognized as a sustainable and reliable method for hydrogen production. Notably, the HER can be coupled with renewable energy sources to achieve zero-carbon hydrogen production, rendering this research topic both pertinent and of profound significance.
Despite the considerable technological progress that has been made over the years, the HER still faces numerous challenges. Fundamentally, the HER is a complex, multi-step electrochemical process occurring at the electrode/electrolyte interface. The development of highly efficient and cost-effective HER electrocatalysts to reduce the onset potential, enhance reaction kinetics, and minimize energy consumption remains one of the most urgent goals in advancing water electrolysis for hydrogen production. In this context, contributions that leverage in situ characterization tools to provide real-time insights into the HER process under operational conditions are particularly encouraged.
For this issue, we welcome original research articles, review papers, and perspectives that explore the latest advancements in the HER. Potential topics of interest include, but are not limited to, the following:
- The design and synthesis of efficient HER electrocatalysts that meet industrial demands for high current density and wide operating temperature ranges, with a particular emphasis on strategies for effective interface gas management.
- In-depth and systematic studies of HER mechanisms under varying pH conditions, offering detailed insights into reaction pathways and kinetics.
- The development of high-performance catalysts for seawater splitting, along with investigations into the underlying reaction mechanisms.
- Explorations of the HER coupled with high-value oxidation reactions, advancing the integration of hydrogen production with economically viable processes.
- The application of advanced in situ and ex situ characterization techniques to the HER, with a focus on accurately identifying catalytic active sites and elucidating their roles in promoting electrocatalytic activity.
Through this Special Issue, we aim to showcase cutting-edge research and provide a platform for the exchange of innovative ideas, driving forward the development of sustainable hydrogen production technologies. Thank you for considering this Special Issue. We look forward to receiving your contributions.
