Abstract
Metal-polyaniline (PANI) composites are provided together with a process of preparing such composites by an electrodeless process. The metal of the composite can have nanoscale structural features and the composites can be used in applications such as catalysis for hydrogenation reactions and for analytical detection methods employing SERS.
Claims12
A method of forming a metal-PANI composite comprising:
- contacting a metal ion solution with a PANI porous asymmetric membrane, wherein the PANI porous asymmetric membrane is doped with an acidic dopant and said metal ion is characterized as its salt form having a reduction potential greater than that of the polyaniline, for a period of time sufficient to deposit the metal onto at least one surface of the membrane.
A method of catalyzing a hydrogenation reaction to obtain a hydrogenated product comprising:
- reacting an unsaturated organic compound with hydrogen for sufficient time in the presense of a metal-PANI composite, wherein the PANI is a porous asymmetric membrane doped with an acidic dopant, and the metal is selected from the group consisting of platinum, palladium and combinations thereof;
- and, recovering a hydrogenated product.
