Atomically precise catalysts are crucial because they allow for unparalleled control over the reaction environment. This precision leads to several advantages: 1. Enhanced Selectivity: By controlling the atomic arrangement, these catalysts can selectively target specific reactions, minimizing side reactions. 2. Increased Efficiency: Uniform active sites lead to more predictable and efficient reactions. 3. Reduced Material Usage: Optimized performance means that smaller amounts of catalyst can achieve the same or better results, reducing costs and environmental impact.
