Discovery of Novel Catalytic Materials for Emissions Control Using High Throughput Scanning Mass Spectrometry

High-throughput approaches were applied to the discovery of more efficient catalysts for various applications in emissions control. The screening approach was based on a hierarchy of qualitative or semi-quantitative primary screens for discovery of hits and quantitative secondary screens for confirmation and scale-up of leads. In this work, primary screening was carried out by fast scanning mass spectrometry (SMS) for NOx abatement, low temperature CO oxidation, VOC removal, COx methanation and the water gas shift (WGS) reaction.
