Nanotechnology has revolutionized the field of catalysis by enabling the synthesis of nanostructured catalysts with exceptional properties. Nanoparticles exhibit high surface area-to-volume ratios, which enhance their catalytic activity. Additionally, the electronic properties of nanoparticles can be tuned through size and shape control, allowing for the optimization of catalytic performance. Techniques such as wet chemical synthesis, sol-gel methods, and chemical vapor deposition are commonly used to fabricate nanocatalysts with precise control over their dimensions and composition.
