The primary goals of long term studies in catalysis include: 1. Evaluating Catalyst Stability: Long term studies help determine how catalysts withstand prolonged exposure to reaction conditions without significant degradation. 2. Understanding Deactivation Mechanisms: Identifying how and why catalysts lose activity over time can lead to the development of more robust materials. 3. Assessing Economic Feasibility: By analyzing the lifespan and performance of catalysts, industries can optimize processes to reduce costs and improve efficiency.
