Deskripsi
Cu-exchanged zeolite chabazite has superior stability over other catalysts in automotive NOx reduction. Here, the authors use atom probe tomography to create 3D nanoscale reconstructions of two Cu-containing zeolite catalysts, providing a complete picture of their deactivation mechanisms during aging.
