Increasing Surface Area: Nanostructured catalysts have a larger surface area, providing more active sites for chemical reactions. Tailoring Active Sites: Specific atomic arrangements and defects at the nanoscale can create highly active sites that are more effective in catalyzing reactions. Improving Stability: Nanostructured catalysts can be engineered to resist sintering and degradation, maintaining their activity over longer periods. Enhancing Selectivity: The precise control over the nanostructure allows for the design of catalysts that favor the formation of specific products, reducing unwanted by-products.
