What are the Challenges in Using Porous Catalysts?
Despite their advantages, the use of porous catalysts also poses certain challenges. These include:
- Pore Blockage: Over time, pores can become blocked by reaction intermediates or by-products, reducing the catalyst's efficiency. - Stability: Some porous materials may degrade under harsh reaction conditions, leading to a loss of porosity and catalytic activity. - Diffusion Limitations: In some cases, the diffusion of reactants and products through the pores can be slow, limiting the overall reaction rate.
