Titanium containing aminoterephthalate metal organic framework promotes the photocatalytic overall water splitting into H-2 and O-2 at a rate that depends on the presence of Pt, RuOx and CoOx co-catalyst. The best values of have been obtained for the MIL-125-NH2 material that contains Pt and RuOx, reaching a production of 218 and 85 mu mol/g (-1)(photocataly)(st) at 24 h for H-2 and O-2, respectively.
