Modified textures and redox activities in Pt/Al2O3 + BaO/CexZr1−xO2 model NSR catalysts

▶ The BaO/CexZr1−xO2 and Pt/Al2O3 mixtures were investigated as NSR catalysts. ▶ Higher Ce content favors rapid NOx up-taking and stable adsorption. ▶ Higher Zr content brings the risk of BaZrO3 formation during the ageing. ▶ The catalyst with strong redox activity limits the NH3 release.
