In situ monitoring of catalytic process variations in a single nanowire by dark-field-assisted surface-enhanced Raman spectroscopy.

In this communication, we provide a new method for characterizing the kinetics of a catalytic process on multiple sites of a single nanowire by dark-field-assisted surface-enhanced Raman spectroscopy (DFSERS). The differences in the reaction rate and the extent of the photocatalysis between sites of a single nanowire were observed.
