Modulating the localized electronic distribution of Cu species during reconstruction for enhanced electrochemical CO₂ reduction to C₂₊ products

Abstract

Electrochemical conversion of carbon dioxide (CO2RR) into high-value multi-carbon (C2+) chemicals and fuels is of great significance for carbon neutrality, and so far the Cu-based materials are still the dominant...

Steady Cu+ species via magnesium and boron co-modification for enhanced CO2 electroreduction to C2+ products: an in situ Raman spectroscopic study

“…After CO 2 activation, Cu δ+ (0 < δ ≤ 1) was proposed to stabilize CO 2 molecules, which can promote the dimerization process between *CO intermediates and enhance the subsequent C-C coupling. 46,47 In addition, we have investigated the effects of Mg on the valence state of Cu compounds, as provided in Fig. 3b and Table S2.…”
