摘要 :

Plasmonic catalysis offers a compelling route for promoting chemical transformations by leveraging intense light-matter interactions and highly localized electromagnetic fields within metallic nanostructures. These phenomena enable the concentration of optical energy and access to reaction pathways that are difficult to realize with conventional catalytic materials. Despite this promise, many plasmonic catalytic systems are still limited by inefficient use of plasmonic excitation, modest intrinsic reactivity, and insufficient control over reactant transport and activation, particularly under dilute reactant conditions. In this talk, I will introduce recent progress from our group in addressing these challenges through the rational design of plasmonic nanocatalysts. Our approach combines hierarchical plasmonic nanoparticles, cooperative nanoparticle assemblies, and purpose-built solid-liquid-gas catalytic interfaces to improve light capture, energy localization, and catalyst-molecule interactions. By concurrently focusing optical energy and regulating molecular behavior at reactive sites, these plasmonic architectures enable more effective light-driven chemical conversions. These advances offer promising pathways toward sustainable energy and environmental technologies, including the efficient light-driven production of green hydrogen and ammonia.
