Core–shell nanoparticle based SERS from hydrogen adsorbed on a rhodium(111) electrodeThis article is part of a ChemComm web-based themed issue on Surface Enhanced Raman Spectroscopy.

We present the first in situsurface Raman spectra of hydrogen on rhodium under electrochemical conditions using gold-core rhodium-shell (Au@Rh) nanoparticles for SERS or gold-core silica-shell (Au@SiO2) nanoparticles for SHINERS. The advantage of SHINERS lies in the versatility to study single crystal surfaces such as the H–Rh(111) system. [ABSTRACT FROM AUTHOR]
