Amorphous-crystalline PdRu bimetallene for efficient hydrogen evolution electrocatalysis†
Abstract
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.
