High-throughput study of the influence of H2O and CO2 on the performance of nitrogen storage and reduction (NSR) catalysts

This paper describes the application of parallel high-throughput experimentation based on FTIR spectral imaging to a tolerance study for NOx storage and reduction (NSR) catalysts with respect to CO2 and H2O in the feed. It was found that both gases decrease the storage capacity of platinum/barium based NSR catalysts, with H2O having a stronger effect than CO2.
