In a groundbreaking development, scientists in Seoul have engineered a solar-powered floating device that simultaneously tackles plastic pollution and generates clean energy. Led by Dr. Lee Wanghee and Prof. Kim Dae-Hyeong, the innovative system uses photocatalysis to convert PET plastic waste into pure hydrogen gas with zero carbon emissions. The technology is remarkably versatile, operating effectively in various water sources, including seawater. This breakthrough offers a scalable and inexpensive path to producing clean hydrogen from everyday waste, presenting a powerful dual solution to the global challenges of plastic pollution and sustainable energy....
