The matrix is crucial for several reasons: 1. Stability: It provides mechanical stability to the catalyst, preventing it from sintering or deactivating under harsh reaction conditions. 2. Dispersion: It helps in the dispersion of active catalytic species, increasing the available surface area for reactions. 3. Accessibility: It ensures that reactants can easily access the catalytic sites. 4. Thermal Conductivity: It can enhance the thermal conductivity, helping in the uniform distribution of heat.
