"Maximizing Solar Energy Output with 2D Supercrystals"

Researchers at LMU's Nano-Institute have developed a two-dimensional supercrystal that generates hydrogen from formic acid using sunlight. The supercrystal, made of gold and platinum nanoparticles, concentrates solar energy and enhances light absorption, resulting in highly localized and strong electric fields. By placing platinum nanoparticles in the hotspots between the gold particles, the researchers achieved a hydrogen production rate of 139 millimoles per hour and per gram of catalyst, setting a world record for H2 production with sunlight. This material solution offers potential for other reactions and could contribute to greener hydrogen production and the conversion of CO2 into usable substances.
