Catalysis is a process that increases the rate of a chemical reaction by adding a substance known as a catalyst. In nanotechnology, the focus is on nanocatalysts, which are catalysts that operate at the nanoscale. Due to their incredibly small size, nanocatalysts have a high surface-to-volume ratio, which significantly enhances their catalytic properties. These materials are pivotal in various industrial processes, such as the production of chemicals, pharmaceuticals, and fuels.
