How Are Nanostructured Silver Catalysts Synthesized?
Several techniques are employed to synthesize nanostructured silver catalysts, including:
1. Chemical Reduction: Silver salts are reduced using reducing agents like sodium borohydride or hydrazine, resulting in the formation of silver nanoparticles. 2. Sol-Gel Method: This involves the transition of a system from a liquid "sol" into a solid "gel" phase, facilitating the formation of nanostructured materials. 3. Electrochemical Deposition: Silver is deposited onto a substrate through the reduction of silver ions in an electrochemical cell, allowing precise control over the nanostructure.
