The rational design of highly efficient catalysts relies
on understanding their structure?activity relationships and reaction
mechanisms at a molecular level. Such an understanding can be
obtained by in situ monitoring of dynamic reaction processes using
surface-sensitive techniques. Surface-enhanced Raman spectroscopy
(SERS) can provide rich structural information with ultrahigh surface
sensitivity, even down to the single-molecule level, which makes it a
promising tool for the in situ study of catalysis. However, only a few
metals (like Au, Ag, and Cu) with particular nanostructures can
generate strong SERS effects. Thus, it is almost impossible to employ
SERS to study transition metals (like Pt, Pd, Ru, etc.) and other
nonmetal materials that are usually used in catalysis ...
