What are Some Challenges Associated with Silica-Supported Catalysts?
Despite its advantages, silica-supported catalysts face certain challenges: - Leaching: The active species may leach from the silica support during the reaction, leading to catalyst deactivation. - Sintering: At high temperatures, the active species may agglomerate, reducing the overall surface area and catalytic activity. - Pore Blockage: The pores of silica can become blocked by reaction by-products, hindering the diffusion of reactants and products.
