Influence of co-catalysts on the photocatalytic activity of MIL-125(Ti)-NH2 in the overall water splitting

[Display omitted] •MIL-125(Ti)-NH2 is a photocatalyst to promote overall water splitting evolving H2 and O2 in stoichiometric amounts.•The presence of co-catalysts increases the activity, reaching a hydrogen production of 218 μmol × g-1.•The maximum quantum efficiency is 0.32 at 400 nm.•MOF stability after the photocatalytic reaction was confirmed by TEM, XRD and XPS analyses. Titanium containing aminoterephthalate metal organic framework promotes the photocatalytic overall water splitting into H2 and O2 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 μmol/g photocatalyst−1 at 24 h for H2 and O2, respectively.
