A convenient setup for laser-induced fluorescence imaging of both CO and CO2 during catalytic CO oxidation

Research output: Contribution to journalArticle

Abstract

In-situ knowledge of the gas composition close to a catalyst is essential for a better understanding of the gas–surface interaction. With planar laser-induced fluorescence (PLIF), the gas distribution around an operating catalyst can be visualized with high spatial and temporal resolution, in a non-intrusive manner. We report on a convenient setup using a nanosecond YAG-Dye laser system together with a broadband mid-infrared optical parametric oscillator (OPO) for imaging both CO and CO2 over a Pd(100) catalyst during catalytic CO oxidation, compare it to previously used systems, and show examples of its capabilities.
