We report a nano-hybrid photo-system based on abundant elements for H2 production with visible light. The photo-system’s proficiency relates to the novel ZnO nanocrystals employed. The ZnO carboxylate oligoethylene glycol shell enhances charge separation and accumulates reactive electrons for the photocatalytic process.
