Abstract | Tip-enhanced Raman spectroscopy (TERS), which combines scanning probe microscopy and plasmon-enhanced Raman spectroscopy, is capable of simultaneously obtaining the topographical and Raman fingerprint information at nanometer spatial resolution. I will introduce our current efforts in developing electrochemical TERS technique as well as some recent studies related to surface and interfaces. The high spatial resolution of TERS allows the identification of the local physicochemical properties of different sites on the nanocatalysts without bothering the averaged effect in ensemble measurement and allows the visualization of the size-specific electronic, geometric and catalytic properties of the different sites on metal as well as two-dimensional materials. |
