Web11 apr. 2024 · Model for a Self-Healing Catalyst. A proposal for the self-healing nature of Pt–Pd catalysts is shown in Figure 9. The PdO traps mobile PtO 2, and as the concentration of Pt builds up, it can transform the oxide into a metal phase. This we feel is the origin of Pt–Pd on one face of the particle, coexisting with PdO. WebLattice Path Enumeration 10.1.
