TLDR
The room temperature dissociation of H(2) on gold nanoparticles using visible light is reported to open a new pathway for controlling chemical reactions on metallic catalysts.Abstract:
Heterogeneous catalysis is of paramount importance in chemistry and energy applications. Catalysts that couple light energy into chemical reactions in a directed, orbital-specific manner would greatly reduce the energy input requirements of chemical transformations, revolutionizing catalysis-driven chemistry. Here we report the room temperature dissociation of H2 on gold nanoparticles using visible light. Surface plasmons excited in the Au nanoparticle decay into hot electrons with energies between the vacuum level and the work function of the metal. In this transient state, hot electrons can transfer into a Feshbach resonance of an H2 molecule adsorbed on the Au nanoparticle surface, triggering dissociation. We probe this process by detecting the formation of HD molecules from the dissociations of H2 and D2 and investigate the effect of Au nanoparticle size and wavelength of incident light on the rate of HD formation. This work opens a new pathway for controlling chemical reactions on metallic catalysts.read more

Aluminum for Plasmonics
TL;DR: This work observes that the energy of the plasmon resonance is determined by, and serves as an optical reporter of, the percentage of oxide present within the Al, and paves the way toward the use of aluminum as a low-cost plAsmonic material with properties and potential applications similar to those of the coinage metals.
