Amorphous-crystalline PdRu bimetallene for efficient hydrogen evolution electrocatalysis.

In this work, PdRu bimetallene is prepared by a wet-chemical method using CO as a structure-directing agent and reductant derived from the decomposition of W(CO) 6 . The PdRu bimetallene exhibits excellent catalytic activity with a small overpotential of -32 mV compared to Pd metallene (-62 mV) at -10 mA cm -2 in acidic conditions.
