Lattice-Hydride Mechanism in Electrocatalytic CO2 ...

2017-7-8 · Copper electrocatalysts can reduce CO 2 to hydrocarbons at high overpotentials. However, a mechanistic understanding of CO 2 reduction on nanostructured Cu catalysts has been lacking. Herein we show that the structurally precise ligand-protected Cu-hydride nanoclusters, such as Cu 32 H 20 L 12 (L is a dithiophosphate ligand), offer unique selectivity for electrocatalytic CO 2 reduction at low ...
