According to foreign media reports, a research team led by Ryuhei Nakamura, the Sustainable Resources Science Center of the Japanese Institute of Science and Chemistry (CSRS), improved their green and sustainable methods, using customized chemical reaction catalysts to extract hydrogen from water.
In the related papers, how to manipulate the 3D structure of the catalyst is described in detail to improve the stability and prolong the life of the catalyst by nearly 4000%.
These findings will contribute to the achievement of a lasting and sustainable hydrogen economy.

The hydrogen produced in this way can be stored for later use.
For example, when used in conjunction with proton exchange membrane (PEM) fuel cells, the stored hydrogen can be used to power electric vehicles.
However, PEM electrolysis still has some limitations, which affect its wide application in power plants and other industrial fields.
In particular, the necessary chemical reactions take place in a highly acidic environment, and the best catalysts for these reactions are extremely rare rare earth metals such as iridium.
“expanding PEM electrolysis to the terawatt scale requires the equivalent of 40 years of iridium, which is undoubtedly impractical and very unsustainable,” Nakamur said.
