Abstract
To employ molecular water reduction catalysts (WRC) in a heterogeneous setup, a stable, macrocyclic CoIII–polypyridyl WRC containing two phosphonic acid groups was anchored on TiO2 to investigate photo- and electrocatalytic proton reduction. Photocatalytic investigations included kinetic studies of the electron transfer from the reduced photosensitizer to the WRC as well as H2-evolution measurements. Linear sweep voltammetry (LSV) performed on the immobilized WRC on a TiO2-coated FTO-glass electrode showed an onset potential of −0.6 V
