Charakterystyka powierzchni materiałów nanostrukturalnych z użyciem powierzchniowo wzmocnionej spektroskopii ramana

Nowadays, surface-enhanced Raman spectroscopy (SERS) is being considered as a rapid and powerful vibrational spectroscopy technique for chemical analysis of materials. The Very high incensement in the intensities of the Raman signal allows for application of that method for chemical analysis of nanostructured surfaces covered with suitable enhancing substrates. For SERS measurements, the substrate plays an essential role because it provides a localized metal surface plasmon resonance enhancement of analyte molecules. Moreover, the use of SERS has a great potential to overcome the Raman spectroscopy weaknesses connected with intensity problems and, therefore, can be applied to the field of heterogeneous catalysts. This article reviews the application of nanoparticles substrates as a ground for SERS enhancement. The article also focuses on the recent progress in SERS characterization of catalytic materials. Recent developments in the field of catalytic material characterization for selected tested molecules allow for performing valuable and reproducible SERS experiments on working catalysts in the reaction environment.
