Recalls in catalysis can occur for various reasons, including:
Performance Degradation: Over time, catalysts may lose their efficiency, leading to suboptimal reactions and economic losses. Contamination: Catalysts can become contaminated with impurities that affect their performance or safety. Safety Issues: Some catalysts may pose health or environmental risks, necessitating their removal from the market. Regulatory Non-Compliance: Changes in regulations can render certain catalysts non-compliant, prompting a recall.
