TLDR
A Pd-Cu bimetallic aerogel electrocatalyst has been developed for conversion of CO2 into CH3 OH and the superior performance results from efficient adsorption and stabilization of the CO2 radical anion, high Pd0 /PdII and CuI +Cu0 /CuII ratios, and sufficient Pd/Cu grain boundaries of aerogels nanochains.Abstract:
Electrochemical reduction of CO2 to CH3 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 CO2 into CH3 OH The current density and Faradaic efficiency of CH3 OH can be as high as 318 mA cm-2 and 800 % over the Pd83 Cu17 aerogel at a very low overpotential (024 V) The superior performance of the electrocatalyst results from efficient adsorption and stabilization of the CO2 radical anion, high Pd0 /PdII and CuI +Cu0 /CuII ratios, and sufficient Pd/Cu grain boundaries of aerogel nanochainsread more

TL;DR: This work finds that at the steady stage of CO2RR, the electrodes have all been reduced to Cu0, regardless of the initial states, suggesting that the high C2+ selectivities are not associated with specific oxidation states of Cu.

TL;DR: A volcano-like curve of the turnover frequency for CO production within the size range suggests that CO2 adsorption, COOH* formation, and CO* removal during CO2 reduction can be tuned by varying the size of Pd NPs due to the changing ratio of corner, edge, and terrace sites.

TL;DR: The results demonstrate that the roughness of oxide-derived copper catalysts plays only a partial role in determining the catalytic performance, while the presence of copper+ is key for lowering the onset potential and enhancing ethylene selectivity.
