Electrocatalytic Surfaces Using Bulk Metallic Glass Nanostructures

Professor André Taylor and co-workers demonstrate how desirable bulk metallic glass compositions can be obtained using a combinatorial approach. It is shown that these alloys can serve as a platform technology for a wide variety of electrochemical applications using a range of surface modification techniques.  Electrochemical devices such as fuel cells, electrolyzers, lithium–air batteries, and pseudocapacitors are expected to play a major role in energy conversion/storage in the future.

Metallic glass nanostructures provide a new platform for electrocatalytic applications. Several surface modification strategies that remove or add metal species (top images) improve the catalytic activity of metallic glass nanostructures.   These strategies were demonstrated for three key electrocatalytic reactions important for renewable energy.
