Highly Efficient Electroreduction of CO2 to Methanol on Palladium–Copper Bimetallic Aerogels
Abstract
Electrochemical reduction of CO 2 to CH 3 OH is of great interest. Aerogels have fine inorganic superstructure with high porosity and are known to be exceptional materials. Now a Pd-Cu bimetallic aerogel electrocatalyst has been developed for conversion of CO 2 into CH 3 OH. The current density and Faradaic efficiency of CH 3 OH can be as high as 31.8 mA cm -2 and 80.0 % over the Pd 83 Cu 17 aerogel at a very low overpotential (0.24 V). The superior performance of the electrocatalyst results from efficient adsorption and stabilization of the CO 2 radical anion, high Pd 0 /Pd II and Cu I +Cu 0 /Cu II ratios, and sufficient Pd/Cu grain boundaries of aerogel nanochains.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
