Abstract:	The steam treatment of Cu-ZSM-5 prepared by solid ion exchange involves an important decrease of the NO conversion. Characterization of the solids by NO-TPD, H₂-TPR, ²⁷Al MAS NMR shows that the catalyst deactivation is mainly due to change in copper species rather than the collapse of the zeolite framework.This revised version was published online in December 2005 with corrections to the Cover Date.

Keywords:	NO-SCR-C₁₀H₂₂ catalyst deactivation hydrothermal treatment Cu-ZSM-5
