Abstract
Harnessing sunlight and storing the energy in chemical bonds is an important element in the transition towards green and sustainable technologies. Solar fuel production requires photocatalysts that (1) absorb large parts of the solar spectrum, (2) generate charges with significant lifetimes and appropriate energies, (3) catalyze relevant chemical transformations from abundant, low-energy starting materials, and (4) are stable under operating conditions. A new avenue within solar fuels involve plasmonic nanocatalysts. These materials have
tunable optical properties, exciting catalytic behavior, and can be more stable under operating conditions. One promising plasmonic nanocatalyst architecture consists of dispersed Pt atoms on plasmonic gold nanoparticles. Here, we study the surface structure and ultrafast dynamics in such Au@Pt core-shell NPs using photoelectron spectroscopy, and femtosecond transient absorption pectroscopy, in view of their potential as plasmonic photocatalysts.
