How Does Phase Composition Affect Catalyst Performance?
The phase composition can influence various aspects of catalyst performance:
Activity: The availability of active sites can be affected by the distribution of different phases. For example, a well-dispersed active metal phase on a support can enhance the activity. Selectivity: Different phases can provide different pathways for the reaction, leading to varying selectivity towards desired products. Stability: The interaction between different phases can influence the thermal and chemical stability of the catalyst. For instance, a strong metal-support interaction can improve the stability of a heterogeneous catalyst.
