When water breaks apart on a well known catalyst, rutile TiO₂, the once-close hydrogen atoms quickly part company in a complicated process, according to scientists at Pacific Northwest National Laboratory (PNNL)'s Institute for Interfacial Catalysis and the University of Texas at Austin. Their detailed study shows the hydrogen atoms are slightly repelled by each other on the surface of rutile TiO₂. The atoms move apart by first sliding an electron over to their new home, then the rest of the atom follows.
