Special Issue Information
Dear Colleagues,
With the rapid growth of the global population and the accelerated development of society, the demand for energy has increased exponentially. However, the excessive use of traditional fossil fuels, such as non-renewable coal, oil, and natural gas, has led to severe environmental issues. Therefore, the exploration of low-carbon and clean energy in order to reduce the emission of greenhouse gases and achieve sustainable development has become a crucial task. Nonetheless, the intermittence and fluctuations in the supply of solar and wind energy limit their large-scale application. Consequently, the development of low-cost, long-life, and high-capacity secondary electrochemical energy storage devices has become a vital means of meeting the energy requirements of portable electronic devices, electric vehicles, and grid storage. Polymer electrolyte membrane fuel cells (PEMFCs) and metal air (oxygen) batteries are among the most promising technologies in this regard. The oxygen reduction reaction (ORR) in the cathode is the key to electrochemical conversion and energy storage, while the sluggish redox kinetics require highly efficient ORR catalysts. Therefore, the development of cost-effective ORR electrocatalysts with enhanced activity and improved durability is crucial for the widespread application of fuel cells. This Special Issue aims to cover recent advances and trends in the synthesis, characterization, and evaluation of advanced ORR electrocatalysts, as well as theoretical insights into the ORR to provide guidance for the rational design of high-performance ORR catalysts.

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. Catalysts is an international peer-reviewed open access monthly 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.
