Recent advance in laser-induced chemical reactions investigated by in-situ Raman spectroscopy

Abstract

In-situ Raman spectroscopy provides a new approach to investigate the photochemical reactions as well as related mechanisms by combining the dual functions of the excitation and in-situ study of chemical reactions. Integrating with our research results, this review summarizes recent advances in laser-induced chemical reactions investigated by in-situ Raman spectroscopy and surface-enhanced Raman spectroscopy (SERS). Firstly, the progress of in-situ SERS study of the surface plasmon (SP)-mediated catalytic reactions is systematically reviewed, where the discovery and development of SP-induced coupling reactions are emphatically introduced. Then, the-state-of-the-art laser-induced chemical reactions monitoring by in-situ Raman spectroscopy is presented. Finally, the problems existing in in-situ Raman spectroscopy study of laser-induced chemical reactions are discussed and the future development is prospected.
