Abstract:
We early demonstrated synergetic effect of Pt and manganese oxides which allows decreasing the Pt loading to 0.7-1.05 g/L in the catalytic system for diesel engine exhaust treatment. Here, we are reporting our study of the effect of Pd addition into Pt-MnOx-Al2O3 monolithic catalysts on their catalytic activity and stability in hydrocarbon and CO oxidation. The synergetic effect in catalytic activity is observed also at Pd addition into Pt-MnOx-Al2O3 catalyst. As result, new diesel exhaust catalyst contains a Pt loading as low as 0.17 g/L at the Pd loading of 0.35 g/L. The PtPd-MnOx-Al2O3 catalyst has high activity in low temperature oxidation of light hydrocarbons and high thermal stability.
We are discussing also Redox properties (TPR-H2), particles size and morphology (HRTEM), and interaction of nanoscale Pt/Pd particles with Mn-modified alumina (chemical differentiating dissolution) in order to explain a positive effect of Pd on catalytic behaviour of Pt-Mn-alumina catalyst.
