To evolve hydrogen with no energy input except sunlight, it is important to develop a stable and efficient catalytic system for water oxidation, which is the much more challenging half reaction of photo-driven water splitting. Molecular and metal oxide catalysts have been used to photochemically oxidize water; however, various approaches still show low catalytic efficiencies. Here we present bio-inspired nanostructures for visible light-driven water oxidation that employs a genetically engineered M13 virus as a scaffold to assemble a hybrid material of porphyrins and iridium oxide nano-clusters. This study suggests that biomimetic, multiscale assembly of functional components, which can improve energy transfer and structural stability, should be a promising route for significant improvement of photocatalytic water splitting. |
