Light-induced hydrogen generation from water catalysed by ruthenium dioxide
Abstract
Ruthenium dioxide, which is known to be a catalyst for the oxidation of water to oxygen, has been observed to mediate hydrogen formation from water in a model system containing Ru(2,2′-bipyridyl)32+, methyl viologen, and ethylenediaminetetra-acetic acid with higher efficiency above pH = 5 than that previously observed with colloidal platinum as catalyst.
