Korean researchers have developed a technology that transforms PET into hydrogen fuel using sunlight and water, aiming to tackle plastic pollution and promote clean energy production.Scientists at the Institute for Basic Science (IBS) Center for Nanoparticle Research, led by Professor Kim Dae-Hyeong and Professor Hyeon Taeghwan from Seoul National University, developed a photocatalytic system that converts PET bottles into hydrogen gas and useful byproducts, such as terephthalic acid, which can be used as a raw material for PET production.
