Web11 de abr. de 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. Web11 de abr. de 2024 · Abstract. Two-dimensional conductive metal–organic frameworks (2D-cMOFs) are a class of 2D layered MOFs with excellent electrical conductivity and other electronic properties. In recent years, their porous structure and dense active sites have been widely used in electrocatalysis and electrochemical sensing.
