Redesigned Catalyst for Producing Hydrogen (image) University of California - Berkeley Share Print E-Mail Caption Molybdenite (top) is a popular catalyst, but reactions take place only at edge sites (circle) where a molybdenum-sulfur-sulfur triangle protrudes. UC Berkeley/LBNL chemists have created molecules (bottom) with only an active site triangle that efficiently convert water to hydrogen.
