The H<sub>2</sub>O Effect on Cu Speciation in Cu-CHA-Catalysts for NH<sub>3</sub>-SCR Probed by NH<sub>3</sub> Titration

The H<sub>2</sub>O Effect on Cu Speciation in Cu-CHA-Catalysts for NH<sub>3</sub>-SCR Probed by NH<sub>3</sub> Titration

The present work is focused on the effect of water on NH<sub>3</sub> adsorption over Cu-CHA SCR catalysts. For this purpose, samples characterized by different SAR (SiO<sub>2</sub>/Al<sub>2</sub>O<sub>3</sub>) ratios and Cu loadings were studied under...
