Increased Surface Area: The high surface-to-volume ratio of nanoparticles provides a greater active surface area for reactions. Enhanced Reactivity: At the nanoscale, materials can exhibit enhanced catalytic properties due to quantum effects and other nanoscale phenomena. Selectivity: Nano-catalysts can be engineered to be more selective, catalyzing specific reactions and minimizing by-products. Sustainability: They often require less material and energy, making processes more sustainable and cost-effective.
