  • Song Jin, a professor of chemistry at the University of Wisconsin-Madison, has reported the highest efficiency ever for a catalyst that splits water and makes hydrogen without using rare, expensive metals. The cobalt-phosphorus-sulfur catalyst can use electricity or sunlight as an energy source.
