Synthetic catalysts are substances that speed up chemical reactions without being consumed in the process. They are often used in industrial applications to enhance the efficiency of reactions, reducing the energy required and increasing product yield. These catalysts can be made from various materials, including metals and organic compounds, and are designed to facilitate specific reactions. One common type of synthetic catalyst is transition metals, which are effective in a wide range of reactions, including hydrogenation and oxidation. Researchers continue to explore new synthetic catalysts to improve processes in fields like pharmaceuticals and green chemistry, aiming for more sustainable and efficient production methods.
