Unique christmas-tree-shaped palladium nanostructures for ascorbic acid oxidation

Palladium nanostructures in the shape of Christmas-tree had created using a simple electrodeposition approach on a Glassy Carbon Electrode (GCE). In alkaline conditions, the modified electrode showed eight times higher catalytic activity than the unmodified GCE for Ascorbic Acid (AA) electro-oxidation. The multiple sharp edges of the hierarchical nanostructures are account for this excellent efficiency.
