The use of biotemplates offers several advantages: 1. Eco-friendliness: Biotemplates are often biodegradable and derived from renewable sources, reducing the environmental impact. 2. Complex Structures: Biological materials have highly complex and hierarchical structures that are difficult to replicate synthetically. 3. Functional Diversity: Biotemplates can introduce a variety of functional groups that can enhance catalytic activity. 4. Scalability: Many biotemplates can be produced in large quantities at relatively low cost.
