A new nickel-based electrocatalyst to produce hydrogen from water.
May 9, 2023
Researchers at the University of Texas at El Paso have proposed a low-cost nickel-based material to make water electrolysis cheaper and more efficient.
Current techniques for splitting low-temperature water rely heavily on platinum as a catalyst, a very expensive material. This fact collides with the growing demand for the installation of electrolysers to produce green hydrogen.
Nickel is an abundant metal on Earth and much cheaper than platinum, but not as effective for low-temperature electrolysis.
The solution devised by the researchers was to enlarge the surface by designing a nanoscale structure.
