Sintering resistant supports work through several mechanisms:
1. Physical Barriers: They provide a physical barrier that prevents the migration and coalescence of metal nanoparticles. 2. Chemical Interactions: Some supports interact chemically with the active metal particles, enhancing their dispersion and stability. 3. Thermal Conductivity: Supports with high thermal conductivity can dissipate heat more effectively, reducing hotspot formation that leads to sintering. 4. Structural Rigidity: Materials with high structural integrity can withstand the mechanical stresses that contribute to sintering.
