  • They utilized supramolecular fluorophore nanocomposite technology to achieve high hydrogen production rates under visible light.
  • The study funded by Korean research foundations showcased the potential of artificial photosynthesis for eco-friendly energy applications.
Professor Chiyoung Park and his team at DGIST, in collaboration with Kyungpook National University, developed a groundbreaking solar-driven biohydrogen production system. By leveraging nanomaterials and tannic acid-based metal-polyphenol polymers, they enhanced fluorescent dye properties for efficient electron transfer. The team's supramolecular photocatalyst mimics natural chlorophyll's electron transfer ability, achieving a significant hydrogen production rate under visible light. Through a bio-composite system with Shewanella oneidensis MR-1 bacterium, they converted vitamin C into hydrogen sustainably. This innovative research sheds light on organic dye mechanisms and artificial photosynthesis, paving the way for future supramolecular chemistry-based energy systems. Funded by Korean research grants, this study marks a milestone in advancing eco-friendly energy solutions.
