What Challenges Exist in the Use of Metal Catalysts?
Despite their effectiveness, the use of metal catalysts poses several challenges. One major issue is the deactivation of catalysts due to sintering, poisoning, or fouling. Sintering involves the aggregation of metal particles, reducing the active surface area. Poisoning occurs when impurities bind to the active sites, rendering them inactive. Fouling refers to the deposition of unwanted materials on the catalyst surface, blocking active sites. Addressing these challenges is essential for the development of more durable and efficient catalysts.
