A University of Wisconsin-Madison and University of Maryland (UM) team has developed a new nanotechnology-driven chemical catalyst that paves the way for more efficient hydrogen fuel-cell vehicles. The team described a new type of catalyst created by surrounding a nanoparticle of ruthenium with one to two layers of platinum atoms. The result is a robust room-temperature catalyst that dramatically improves a key hydrogen purification reaction and leaves more hydrogen available make energy. (source: news.wisc.edu)
