Special Issue Information
Dear Colleagues,
The main challenge for a secure human society is meeting the energy demand of fuels and other materials while achieving environmental sustainability. Catalysts play a crucial role in modern industry because they possess active sites that convert undesirable substances in air or water into desirable products. In recent years, great efforts have been made to convert the greenhouse gas carbon dioxide (CO2) into value-added chemicals. Moreover, lowering the CO2 levels in the atmosphere has become a critical challenge for sustainable development and decoupling economic growth. A recommended technology for CO2 utilization to produce various commodity chemicals is electrochemical reduction. However, when CO2 is reduced electrochemically, multiple reaction pathways are involved, leading to the non-selective production of different products. The formation of a mixture of products decreases the value of the products formed. Other factors, such as catalyst type, reaction conditions, electrolyte composition, applied potential, and reaction time, can greatly influence the efficiency of the CO2 reduction process. Additionally, in aqueous electrolyte solutions, the competing hydrogen evolution reaction (HER) creates a major challenge, as both reactions occur at the same reaction potential. Therefore, designing an electrocatalyst that selectively promotes CO2 reduction and suppresses the HER process is of prime importance for creating a more sustainable economy.
The aim of this Special Issue is to provide a collective overview of current research on the electroreduction of CO2 and innovative catalyst design approaches that can overcome current limitations. We welcome researchers to submit their original research articles, reviews, and short communications within the topic of interest. Also, mechanistic and fundamental studies related to this research are appreciated.

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 250 words) can be sent to the Editorial Office for assessment.
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. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
