Researchers in Japan have developed an inexpensive, high-performance catalyst for hydrogen storage using a modified form of ‘green rust,’ a common iron hydroxide mineral.
The work, conducted at the National Institute for Materials Science (NIMS), demonstrates a method to release hydrogen from sodium borohydride (NaBH4) without relying on costly precious metals like platinum. This addresses a key obstacle in the use of hydrogen as a clean fuel.
“We expect that our catalyst will be used for hydrogen fuel cells in many onboard applications like cars and ships,” said Dr. Yusuke Ide, who led the research team.
“This will hopefully lead to various forms of emission-free mobility.”
