What are Some Common Methods for Catalyst Synthesis?
Catalyst synthesis can be broadly categorized into several methods: 1. Precipitation and Co-precipitation: Involves the formation of a solid catalyst from a solution. This method is often used for making metal oxides and mixed-metal oxides. 2. Sol-Gel Method: Involves the transition of a solution (sol) into a solid (gel) phase. This technique is versatile and can produce catalysts with high surface areas and controlled pore sizes. 3. Impregnation: A solution containing the active component is impregnated onto a support material, followed by drying and calcination. 4. Deposition-Precipitation: Similar to impregnation, but the active component is precipitated onto the support from a solution. 5. Chemical Vapor Deposition (CVD): Involves the deposition of a thin film of the active component onto a substrate from a vapor phase.
