Investigation of the mechanisms of plasmon-mediated photocatalysis: synergistic contribution of near-field and charge transfer effects
Zelio Fusco, Kylie Catchpole, Fiona J. Beck
Abstract
We demonstrate that hot carriers and optical near-fields synergistically cooperate to drive the N -demethylation reaction of methylene blue adsorbed on plasmonic nanoparticles, and show that photothermal effects do not play a dominant role.
