Researchers have developed a groundbreaking solar hydrogen production technology by utilizing a supramolecular nanocomposite fabrication technique. By coating self-assembled nanospheres with metal-phenolic polymers, the team induced supramolecular reconstruction, enhancing stability and electron transfer during photocatalytic reactions. This innovative hybrid system significantly increased both hydrogen production and the sustainability of continuous reactions. The study, published in Angewandte Chemie International Edition, was led by Professor Hyojung Cha and Professor Chiyoung Park. They successfully integrated a supramolecular dye with bacteria, specifically Shewanella oneidensis MR-1, creating a bio-composite system capable of converting vitamin C into hydrogen using sunlight. The system demonstrated remarkable stability and continuous hydrogen production. Professor Park emphasized the study's importance in unraveling the mechanisms of organic dyes and artificial photosynthesis. Future research will focus on developing new supramolecular systems that combine functional microorganisms with novel materials, paving the way for advanced solar energy utilization.
