Table 1. Summarized results of homogeneous and heterogeneous photocatalytic H2 production in 10 mL aqueous 1 M ascorbate buffer (pH 4) with 0.1 M NaOTf. Bold: 3 and 5 immobilized on f-SiO2-C18, 15 μM surfactant 7 per μM PS 5 and 0.1 M NaOTf. Italic font: homogeneously dissolved [Ru(bpy)3]Cl2 and 1. Rate courses and produced hydrogen of 20/1 and 10/0.5 μM PS/WRC are depicted in Fig. 3 .
