Abstract

Toward complete artificial photosynthesis systems to generate hydrogen and oxygen using visible light and water, we firstly design and fabricate oxygen-generating gel systems using the electrostatic interactions of ionic functional groups and steric effects of a polymer network. By using a graft polymer chain with Ru(bpy)32+ units as sensitizers to closely arrange RuO2 nanoparticles as catalyst, the functional groups transmit multiple electrons cooperatively to generate oxygen. In this study, a novel strategy is shown to design a hierarchical network structure using colloidal nanoparticles and macromonomers.
