About this Research Topic

Background

Electrocatalysis is a pivotal field in the quest for sustainable energy solutions. With global warming posing a significant threat, the reliance on fossil fuels, which account for over 80% of global energy demand, has led to alarming levels of carbon emissions. As of July 2023, atmospheric CO2 levels reached 422 ppm, exacerbated by a growing global population and rapid industrialization. Projections indicate that if current trends continue, we will surpass the global carbon budget by 2050, leading to catastrophic climate consequences. The urgent need to transition to green and renewable energy sources is evident. Electrocatalysis offers a promising avenue, enabling the conversion of chemical energy into electricity and vice versa, with hydrogen emerging as a key player. Hydrogen, produced via water electrolysis, can be stored, transported, and reconverted into electricity, presenting a sustainable alternative to fossil fuels. Despite significant advancements, there remain gaps in our understanding and application of electrocatalytic processes, necessitating further research to optimize these technologies and reduce CO2 emissions.

This Research Topic aims to gather significant breakthroughs in the electrocatalysis field that will help achieve a more sustainable energy landscape in the following years. The primary objective is to explore innovative electrocatalysts and devices for electrochemical energy conversion, enhancing our understanding of electrocatalytic reactions. Key questions include identifying the most efficient materials and methods for electrocatalysis, understanding the underlying mechanisms of these reactions, and developing scalable technologies for practical applications. Hypotheses to be tested may involve the efficiency and stability of new electrocatalysts, the impact of different environmental conditions on electrocatalytic performance, and the potential for integrating these technologies into existing energy systems.

To gather further insights in the realm of electrocatalysis, we welcome articles addressing, but not limited to, the following themes:

- Electrocatalysis
- Interfacial Electrochemistry
- Physical Methods for the Study of Electrode Surfaces and Interfaces
- Computational Simulations in Electrochemistry
- Electrochemical Engineering
- Electrochemical Materials Science
- Fuel Cells
- Water Electrolyzers
- CO2 Electrolyzers
- Electrosynthesis

By exploring these themes, we aim to foster a comprehensive understanding of electrocatalysis and its potential to revolutionize the energy landscape, paving the way for a more sustainable future.

Frequently asked questions

• What is a Research Topic?

  Frontiers' Research Topics are collaborative hubs built around an emerging theme.Defined, managed, and led by renowned researchers, they bring communities together around a shared area of interest to stimulate collaboration and innovation.

  Unlike section journals, which serve established specialty communities, Research Topics are pioneer hubs, responding to the evolving scientific landscape and catering to new communities.

• Why does Frontiers publish Research Topics? 

  The goal of Frontiers' publishing program is to empower research communities to actively steer the course of scientific publishing. Our program was implemented as a three-part unit with fixed field journals, flexible specialty sections, and dynamically emerging Research Topics, connecting communities of different sizes and maturity.

  Research Topics originate from the scientific community. Many of our Research Topics are suggested by existing editorial board members who have identified critical challenges or areas of interest in their field.

• Why are Research Topics important for journals?

  As an editor, Research Topics will help you build your journal, as well as your community, around emerging, cutting-edge research. As research trailblazers, Research Topics attract high-quality submissions from leading experts all over the world.

  A thriving Research Topic can potentially evolve into a new specialty section if there is sustained interest and a growing community around it.

• How do we ensure the quality of articles within Research Topics?

  Each Research Topic must be approved by the specialty chief editor, and they fall under the editorial oversight of our editorial boards, supported by our in-house research integrity team. The same standards and rigorous peer review processes apply to articles published as part of a Research Topic as for any other article we publish.

    In 2023, 80% of the Research Topics we published were edited or co-edited by our editorial board members, who are already familiar with their journal's scope, ethos, and publishing model. All other topics are guest edited by leaders in their field, each vetted and formally approved by the specialty chief editor.

• What are the benefits of publishing my article in a Research Topic?

  Publishing your article within a Research Topic with other related articles increases its discoverability and visibility, which can lead to more views, downloads, and citations. Research Topics grow dynamically as more published articles are added, causing frequent revisiting, and further visibility.

  As Research Topics are multidisciplinary, they are cross-listed in several fields and section journals – increasing your reach even more and giving you the chance to expand your network and collaborate with researchers in different fields, all focusing on expanding knowledge around the same important topic.

  Our larger Research Topics are also converted into ebooks and receive social media promotion from our digital marketing team.

   
• What types of articles can be published in a Research Topic?
