Modification of oxysulfides with two nanoparticulate cocatalysts to achieve enhanced hydrogen production from water with visible light.
Modification of oxysulfides, such as Sm(2)Ti(2)S(2)O(5) and Gd(2)Ti(2)S(2)O(5), with nanoparticulate Rh (reduction site) and Ag(2)S (oxidation site) resulted in enhanced H(2) production from water containing Na(2)S and Na(2)SO(3) as electron donors, showing an apparent quantum yield of 8.8% at 440 nm. This was approximately 9 or 160 times the yield achieved using samples modified with Rh or Ag(2)S, respectively.
