What Are the Challenges in Using Catalyst Particles?
Despite their advantages, catalyst particles face several challenges. Deactivation due to sintering, poisoning, or fouling can reduce their effectiveness over time. Sintering occurs when particles agglomerate at high temperatures, reducing surface area. Poisoning happens when impurities bind to active sites, rendering them inactive. Fouling involves the accumulation of by-products on the catalyst surface, blocking active sites.
