'Artificial leaf' uses visible light to accelerate chemical reactions

Wed, 11/28/2018 - 12:50
Over the past several years, metal nanoparticles photosensitization over semiconductors with a large band gap has emerged as a promising strategy for developing visible-light responsive photocatalytic materials. In new work, researchers demonstrate a new plasmonic metamaterial can absorb nearly 100% of incident light (of a specific color) and use this energy to accelerate the production of chemicals. In constructing the near-perfect absorber, the researchers employ gold nanoparticles, TiO2 as the spacer layer, and a continuous gold thin film as the rear reflective layer.
