Small changes go a long way: Modification of the terminal ligand to incorporate 4,7-diphenyl-1,10-phenanthroline has generated superior Ru,Rh,Ru photocatalysts (see scheme; ochre Ru, red Rh, blue N, yellow Cl or Br) displaying significantly enhanced photocatalytic H 2 production from H 2O with long-term functioning: H 2O is reduced to H 2 with over 1300 turnovers per Rh site and a maximum efficiency of 7.3-%. © 2011 WILEY-VCH Verlag GmbH & Co.
