High electrocatalytic activity for borohydride oxidation on palladium nanocubes enclosed by {200} facets

A 7e reaction is realized on the Pd nanocubes enclosed by {200} facets at a high borohydride concentration of 3.26 M. The direct borohydride fuel cells using Pd nanocubes as anode catalyst have higher power density and much better stability than commercial Pd/C.249
