  1. 1. Palladium-based Nanoplasmonics for Ultrafast and Deactivation-Resistant Hydrogen Detection

    Författare :Iwan Darmadi; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plasmonic sensing; palladium hydride; palladium; polymer; localized surface plasmon resonance; Pd; nanoparticle; surfactant; hydrogen; palladium alloy; hydrogen sensor;

    Sammanfattning : In the hydrogen economy scenario, hHydrogen gas is ispotential to be the main energy carrier in the hydrogen economy scenario in the upcoming future. It receives much attention since the reaction with oxygen generates electricity and produces only clean waterhydrogen is attractive as energy carrier since the energy produced by its reaction with oxygen only producesleaves water as by-product.

    Sammanfattning : Plasmonic metal nanoparticles and polymer materials have independently undergone rapid development during the last two decades. More recently, it has been realized that combining these two systems in a hybrid or nanocomposite material comprised of plasmonically active metal nanoparticles dispersed in a polymer matrix leads to systems that exhibit fascinating properties, and some first attempts had been made to exploit them for optical spectroscopy, solar cells or even pure art.
