A novel MOF-derived strategy to construct Cu-doped CeO2 supported PdCu alloy electrocatalysts for hydrogen evolution reaction

Rare earth oxide based electrocatalysts: synthesis, properties and applications

“…Chen et al constructed a bimetallic MOF derivative strategy, achieved parallel doping and alloying of transition metals, and prepared Pd–CuCeO x catalysts with Cu as the dopant element in CeO 2 and the secondary metal in Pd–Cu alloys. 90 The synthesized catalysts require an overpotential of only 109 mV to achieve a current density of 10 mA cm −2 , and its Tafel slope is only 30.9 mV dec −1 . Pd–CuCeO x with low precious metal content has a TOF of as high as 6.99 s −1 , which is about 3.5 times that of commodity Pt/C.…”
