Researchers from Yale University and the University of Missouri have conducted a study demonstrating that chemical catalysts containing manganese can convert carbon dioxide into formate. Formate has been identified as a potential source of hydrogen, which is utilized in next-generation fuel cells. The findings contribute to ongoing efforts to develop cost-efficient methods for hydrogen production and storage, critical aspects for the broader implementation of fuel cell technology, and to advance the use of carbon dioxide in renewable chemical feedstocks.
Research Findings
The study focused on the effectiveness of chemical catalysts containing manganese, an abundant and cost-effective metallic element, in facilitating a chemical reaction that transforms carbon dioxide into formate. Formate is recognized for its potential to supply hydrogen, which can then be used in advanced fuel cell applications.
Implications for Energy Technology
Hydrogen fuel cells operate by converting chemical energy from hydrogen into electricity. A primary challenge for the widespread adoption of this technology involves establishing cost-efficient methods for both the production and storage of hydrogen. The conversion of carbon dioxide to formate, a potential hydrogen source, addresses this challenge. Additionally, the utilization of carbon dioxide is a current priority in the development of renewable chemical feedstocks, aimed at replacing those derived from fossil fuels.
Study Details
The findings of this research were published in the journal Chem. The lead authors of the study were Justin Wedal, a postdoctoral researcher at Yale, and Kyler Virtue, a graduate research assistant at the University of Missouri. Senior authorship for the study was attributed to Professor Nilay Hazari of Yale University and Professor Wesley Bernskoetter of the University of Missouri. Professor Hazari holds the position of John Randolph Huffman Professor of Chemistry and chairs the chemistry department in Yale’s Faculty of Arts and Sciences.
