| Abstract Scope |
The chemistry and morphology of catalytic amorphous metals may be tuned to obtain hierarchical nanostructures for clean energy applications. Accelerated development of electro-catalysts requires efficient synthesis of morphologies that provides effective utilization of the active catalytic species and high dispersion. Unique combination of desirable properties and processing ability in metallic-glasses make them attractive for catalysis. Using scanning electrochemical microscopy (SECM) and scanning kelvin probe (SKP), we have mapped the electrochemical activity of a series of metallic glasses and show their efficacy in a number of catalytic reactions for fuel cells. Using this knowledge, we synthesized non-precious metallic glass compositions with high catalytic performance and good chemical stability as potential replacement of expensive noble metal catalysts.
