Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

This discovery paves the way for sustainable, low-cost hydrogen that could be produced locally rather than in massive centralized plants. It also demonstrates that photocatalysis can be efficiently performed with inexpensive LED photon sources. —co-author Naomi Halas. —Peter Nordlander, co-author.
