Green hydrogen - produced from water electrolysis by using sustainable electricity - is getting more attention due to its potential to be used as energy carrier as well as building block for various industrial processes. Among both half-reactions of water electrolysis, Oxygen Evolution Reaction ...
Researchers take key step toward cleaner, more sustainable production of hydrogen
Efficiently mass-producing hydrogen from water is closer to becoming a reality thanks to Oregon State University College of Engineering researchers and collaborators at Cornell University and the Argonne National Laboratory. The scientists used advanced experimental tools to forge a clearer ...
Recent years have witnessed explosive development in electrochemical CO2 reduction into valuable chemicals or fuels. The CO2 electroreduction is considered as a promising route to utilize renewable electricity from intermittent energy, such as solar, winder, geothermal power, etc. Designing ...
Electrocatalyst without a carbon carrier developed
An international research team led by the University of Bern has succeeded in developing an electrocatalyst for hydrogen fuel cells which, in contrast to the catalysts commonly used today, does not require a carbon carrier and is therefore much more stable. The new process is industrially ...
What would have to change in research to develop efficient, stable and selective catalysts for industrial application?
Efficient catalysts are crucial for energy conversion. However, findings from basic research rarely make it into practice at present. Regenerative energy harvesting often generates more electricity than is directly needed. Electrochemical processes could be used to store the excess energy or make ...
New breakthroughs in computational quantum chemistry, hold promise for discovering catalysts that are "just right" and thousands of times faster than standard approaches
Developing catalysts for sustainable fuel and chemical production requires a kind of Goldilocks Effect - some catalysts are too ineffective while others are too uneconomical. Catalyst testing also takes a lot of time and resources. New breakthroughs in computational quantum chemistry, however, ...
New electrocatalyst efficiently converts carbon dioxide into ethanol
Catalysts speed up chemical reactions and form the backbone of many industrial processes. For example, they are essential in transforming heavy oil into gasoline or jet fuel. Today, catalysts are involved in over 80 percent of all manufactured products. A research team, led by the U.S. Department ...
KAIST researchers developed a three-dimensional (3D) hierarchically porous nanostructured catalyst with carbon dioxide (CO2) to carbon monoxide (CO) conversion rate up to 3.96 times higher than that of conventional nanoporous gold catalysts. This new catalyst helps overcome the existing ...
New method provides fundamental insights into electrocatalytic water splitting under operating conditions
Whether as a fuel or in energy storage: hydrogen is being traded as the energy carrier of the future. To date, existing methodologies have not been able to elucidate how exactly the electrochemical process of water splitting into hydrogen and oxygen takes place at the molecular scale on a ...
Electrocatalysts can help to obtain chemicals from renewable raw materials or to use alternative energy sources. But testing new catalysts brings challenges. Researchers at the Ruhr-Universität Bochum (RUB) and the University of Duisburg-Essen have developed a new method of depositing catalyst ...
