Tuning the Pd-catalyzed electroreduction of CO 2 to CO with reduced overpotential

Abstract:

Developing selective and efficient catalysts is highly desirable for electrochemical CO2reduction (ECR) to fuels and chemicals. Pd can strongly bind ∗COOH but weakly bind ∗CO, thus resulting in CO as a product. However, proton reduction also occurs severely on the surface of Pd, leading to low CO selectivity. Here we found that the ECR to CO can be greatly enhanced by controlling the Pd-ceria interface and doping with tellurium atoms. Notably, a very high mass activity of 92 mA mgPd-1(at 1.0 ...
