What are the Challenges in Using Silica-Based Catalysts?
Despite their advantages, silica-based catalysts face several challenges:
Pore Blocking: The pores of silica can become blocked by reaction intermediates or products, reducing catalyst efficiency. Leaching: Active species can leach from the silica support, leading to catalyst deactivation. Thermal Degradation: Although silica is thermally stable, prolonged exposure to extreme temperatures can lead to structural changes.
