✦ Synopsis

The non-biomimetic splitting of water has been achieved using a single photocatalyst-catalyst (tris-[l-(4-metho~henyl-2-phenyl-1,2-ethylenodithiolenic-S,S']tungsten), and a reversible electron acceptor (methylviologen).

The average quantum yield (in equivalents) in the effective wavelength range in the visble (400-500 nm) is about 4%. The oxidation and reduction cycles of water are fully coupled, in fact they are integrated, in the sense that they are part of a single cycle, rather than of the separate hypothetical cycles with contact points proposed in the literature.
