5 Times More Effective Bi-Metallic Catalyst
16 May 2009 | Green News | 1 Comment
Researchers from Washington University, lead by Younan Xia, Professor of Biomedical Engineering, has developed a bimetallic catalyst that is almost five times more efficient than other commercial catalysts.This type of catalysts could enable some cheaper fuel cell technology.The operation principle of this technology is based on the use of platinum and palladium and also using nanotechnology.
“Catalyst is said to be comprised of platinum and palladium that supports dendritic platinum branches, or arms, that are fixed on the nanostructure, consisting of a nine nanometer core and seven nanometer platinum arms. Due to this very reason, it can reduce precursor compound to palladium and platinum with L-ascorbic acid, commonly known as Vitamin C. Further, the high surface area of catalyst makes it suitable not only for fuel cell, but for many other applications. Researchers claim that this technique is two to five times more effective than commercial catalysts. According to the Department of Energy, reduction in the amount of platinum catalyst, that is considered one of the most expensive, can bring down the cost of fuel cell. Further, researchers are experimenting with other noble materials like such as gold that can be added to bimetallic catalysts to convert them into trimetalic. ” – www.ecofriend.org
