Plasmonic Platform Enhances Photocatalysis
HOUSTON and CAMBRIDGE, England, Oct. 11, 2017 — Researchers have developed a way to build multifunctional nanoscale structures using aluminum nanocrystals. The structures have an aluminum core and are dotted with even smaller metallic islands. The nanocrystals are used as a base for creating size-tunable transition-metal nanoparticle islands that enable localized surface plasmon resonances. According to researchers, aluminum is an effective plasmonic material, and adding smaller catalytic particles from three columns of the periodic table
