How are nanomaterials synthesized for catalytic applications?
Several methods are used to synthesize nanomaterials for catalytic applications, including: 1. Chemical Vapor Deposition (CVD): A process where gaseous reactants form a solid material on a substrate. 2. Sol-Gel Processing: A method involving the transition of a solution system from a liquid "sol" into a solid "gel" phase. 3. Hydrothermal Synthesis: Involves the crystallization of substances from high-temperature aqueous solutions at high vapor pressures. 4. Electrodeposition: A technique where an electric current is used to reduce metal cations from a solution to form a coating on a substrate.
