Efficient Photocatalytic Hydrogen Production in a Single-Component System Using Ru,Rh,Ru Supramolecules Containing 4,7-Diphenyl-1,10-Phenanthroline

Efficient Photocatalytic Hydrogen Production in a Single-Component System Using Ru,Rh,Ru Supramolecules Containing 4,7-Diphenyl-1,10-Phenanthroline

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 H2 production from H2O with long‐te...

Zusammenfassung: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 H2 production from H2O with long‐term functioning: H2O is reduced to H2 with over 1300 turnovers per Rh site and a maximum efficiency of 7.3 %.
