There are several strategies to mitigate the toxicity of catalysts:
1. Substitution with Non-Toxic Alternatives: Researchers are continuously seeking and developing less toxic catalysts. For example, replacing chromium-based catalysts with iron-based alternatives in certain reactions.
2. Encapsulation: Encapsulating toxic catalysts in inert materials can prevent their release into the environment and reduce human exposure.
3. Recycling and Reuse: Efficient recycling of catalysts can minimize environmental contamination and reduce the need for raw toxic materials.
4. Green Chemistry Principles: Applying the principles of green chemistry can help in designing safer catalytic processes.
