Professor Chiyoung Park from Daegu Gyeongbuk Institute of Science and Technology innovatively developed a solar-powered biohydrogen production system using nanomaterials and a supramolecular fluorophore nanocomposite technology. The research, published in Angewandte Chemie International Edition, compared organic biological systems to create a highly efficient biohydrogen generation system. By leveraging the nanosurface adsorption properties of tannic acid-based metal-polyphenol polymers, Park and his team regulated self-assembly and optical properties of fluorescent dyes, leading to the creation of a unique photocatalyst resembling chlorophyll's electron transfer processes. The system incorporated bacteria-carrying hydrogenase enzymes to continuously produce hydrogen under sunlight. This breakthrough achieved a hydrogen production rate 5.6 times higher than previous studies, demonstrating remarkable efficiency. Supported by Korean research foundations, this study sheds light on novel mechanisms in organic dyes and artificial photosynthesis, paving the way for future research in sustainable energy solutions.
