Pretty exciting development to convert water to hydrogen and oxygen appears in http://www.sciencemag.org/cgi/content/abstract/science.1185372" ).
The catalyst is based on Co4O4 stabilized with bulky polytungstate ligands. The best part is that the complex spontaneously organizes into the active form by combining salts of cobalt, tungsten and phosphate. It doesn't get much easier than that! Tris-(2,2'-bipyridyl)ruthenium(III) is reported to by the oxidant in the photocycle but its stability in the cycle isn't mentioned. If the ruthenium oxidant is recycled this could be really big. I can't wait to read the hardcopy.
WOW! Could cheap abundant high purity hydrogen be just around the corner?
