High yield hydrogen production! Scientists successfully developed
An international research team led by Peking University has successfully developed a new hydrogen production method that eliminates carbon dioxide emissions at source through a new catalyst to achieve high-yield hydrogen production. The breakthrough was published in the international academic journal Science on February 14.
Hydrogen energy, as a clean energy with development potential, is one of the focuses of accelerating development and utilization in the world. However, traditional methods of producing hydrogen from fossil fuels, including ethanol, typically require high temperatures of 300 to 1,200 degrees Celsius and produce large amounts of carbon dioxide.
Peking University, together with the University of Chinese Academy of Sciences and Cardiff University in the United Kingdom, has developed a new type of platinum-iridium bimetallic catalyst for ten years, successfully breaking the technical bottleneck of traditional ethanol hydrogen production. With this catalyst, the bioethanol converted from agricultural and forestry waste can be directly converted into clean hydrogen by reacting with water molecules at only 270 degrees Celsius to achieve high-yield hydrogen production.
Martin, the corresponding author of the paper and a professor at the School of Chemistry and Molecular Engineering at Peking University, said that this catalyst changes the chemical reaction path by accurately regulating the active site, so that the carbon atoms in the ethanol molecule are captured into the acetic acid product, so as to achieve the chemical reaction without releasing carbon dioxide and directly generate hydrogen.
In addition to its considerable environmental benefits, the technology is economically viable, allowing for the simultaneous production of hydrogen and high-value chemicals from biomass, particularly acetic acid, which has important industrial value. "The simultaneous production of acetic acid in the chemical reaction enhances the economic viability and sustainability of this green technology, helping to create a new circular economy model in the future that not only reduces carbon emissions, but also enables efficient use of resources." "Martin said.
