Heterogeneous vs. Homogeneous Catalysis: Comparative Insights and Breakthroughs
Abstract: Catalysis, a pivotal process in chemical reactions, can be classified into two main types: heterogeneous and homogeneous catalysis. This comparative analysis delves into the distinctions, advantages, and breakthroughs in both domains. Heterogeneous catalysis, involving catalysts in a different phase than the reactants, is characterized by ease of separation and catalyst recovery, making it industrially favorable. Conversely, homogeneous catalysis, where catalysts and reactants share the same phase, offers superior selectivity and …
