Iron plus UV light turns alcohol into hydrogen with catalyst-like efficiency

Phys · · 537 words · By Kyushu University
Green Chemistry Scientific Innovation Sustainable Energy

Researchers from Kyushu University have developed a method to produce hydrogen gas using a mixture of methanol, sodium hydroxide, and iron ions under UV light. The study, published in Communications Chemistry, indicates that this simple process can also work with other alcohols and biomass-derived materials.
