  • Colorful chemistry. Specially designed nanoparticles of electrically conductive plastic (here in water) are a key ingredient in the researchers' new recipe for how hydrogen from solar energy can be produced efficiently without the expensive scarce metal platinum. The nanoparticles interact with the light around them, causing them to absorb different colors and take on all the shades of the rainbow. Through advanced material design, a research team, led by Chalmers, has changed the properties of the plastic and its nanoparticles in water, which greatly improves the chemical process when hydrogen is produced from sunlight.
