Of the different Fe\u2010Beta zeolites, the sample prepared in the absence of alkali cations with a Si\/Al ratio of around 13 showed high NO conversion values (&gt;90\u2009%). However, this catalyst suffered from severe deactivation when aged at high temperatures in the presence of steam. The preparation of more hydrophobic Fe\u2010Beta zeolites did not improve the resistance of the catalyst against steam.
