Abstract

A graphene oxide (GO) and ruthenium(II) complex with bromine-substituted terpyridine ligand, [Ru(Br-terpy)2]Cl2 (Br-terpy: 4′-bromo-2,2′:6′,2′′-terpyridine), reacts to form a GO–[Ru(Br-terpy)2]2+ hybrid, which after photoreduction turns to the reduced graphene oxide (rGO)-based hybrid rGO–[Ru(Br-terpy)2]2+. The hybrids were characterized by UV, IR, and XPS spectra. rGO–[Ru(Br-terpy)2]2+ exhibits excellent photocurrent generation through the cathodic photoreduction process. This observation indicates the possibility of designing an rGO-based energy generating material.
