Special Issue Information
Dear Colleagues,
The electrochemical reduction of CO2 (CO2RR) is a promising approach to converting CO2 into value-added fuels and chemicals using renewable electricity, offering a sustainable means of carbon management and energy production. In recent years, we have witnessed significant advances in the development of electrocatalysts, the optimization of reactor designs, and the enhancement of system efficiency. However, challenges such as catalyst stability, product selectivity, competitive hydrogen evolution, and scale-up limitations must be addressed to advance CO2RR for industrial implementation.
This Special Issue aims to showcase recent developments in CO2 electrolysis, covering key aspects such as catalyst design, reaction mechanisms, electrolyte and reactor optimization, product purification, and system integration. Additionally, we welcome contributions that present approaches to CO2 capture and purification that are tailored to electrochemical conversion.
The scope of this Special Issue includes, but is not limited to, the following topics:
- Development and characterization of electrocatalysts;
- Mechanistic studies and theoretical modelling;
- Electrolyte and reactor design for improved performance;
- Strategies to enhance product selectivity and energy efficiency;
- Product collection, separation, and industrial applications;
- Integration of CO2 capture with electrochemical conversion.
We welcome original research articles, reviews, and perspectives that advance our understanding and practical implementation of CO2RR, contributing to scalable and sustainable carbon conversion technologies.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Energies is an international peer-reviewed open access semimonthly journal published by MDPI.
