Fig. 2. Hydrogen evolution rate courses (solid lines) and total amounts of H2 (dotted lines) in 1 M ascorbate buffer (pH 4) with 0.1 M NaOTf. Black: 20 μM 3 and 200 μM 5 adsorbed on hydrophobic fumed silica with 300 μM [C16-NMe3][OAc] (7) as surfactant. Green: same as black, but loaded silica was filtered off and the residual solution irradiated, then 0.5 mM [Ru(bpy)3]Cl2 was added and irradiation continued (green arrows). Red: 0.5 mM [Ru(bpy)3]Cl2, no WRC. See Table SI3.† .
