Electrocatalytic CO2-to-C2+ with Ampere-Level Current on Heteroatom-Engineered Copper via Tuning *CO Intermediate Coverage.

Journal of the American Chemical Society, 2022
An ampere-level current density of CO2 electrolysis is critical to realize the industrial production of multicarbon (C2+) fuels. However, under such a large current density, the poor CO intermediate (*CO) coverage on the catalyst surface induces the ...

C2+ Selectivity for CO2 Electroreduction on Oxidized Cu-Based Catalysts.

Journal of the American Chemical Society, 2023
Design for highly selective catalysts for CO2 electroreduction to multicarbon (C2+) fuels is pressing and important. There is, however, presently a poor understanding of selectivity toward C2+ species.

High-Power CO2-to-C2 Electroreduction on Ga-Spaced, Square-like Cu Sites.

Journal of the American Chemical Society, 2023
The electrochemical conversion of CO2 into multicarbon (C2) products on Cu-based catalysts is strongly affected by the surface coverage of adsorbed CO (*CO) intermediates and the subsequent C-C coupling.

Industrial-Current-Density CO2-to-C2+ Electroreduction by Anti-swelling Anion-Exchange Ionomer-Modified Oxide-Derived Cu Nanosheets.

Journal of the American Chemical Society, 2022
CO2 electroreduction to high-energy-density C2+ products is highly attractive, whereas the C2+ selectivity under industrial current densities is still unsatisfying.

Theoretical study of C2 and C2−

The Journal of Chemical Physics, 1980
Potential energy curves of the ground states of C2(X 1Σg+) and C2−(X 2Σg+) have been calculated using SCF, MCSCF, and CI methods. Close agreement with experimental dissociation energies, bond lengths, and spectroscopic constants is obtained by a CI calculation including all single and double excitations from the restricted Hartree–Fock configuration ...

Study on the analytical potential energy function for C2, C2+ and C2−

Journal of Molecular Structure: THEOCHEM, 2001
Abstract The present work has derived the potential energy functions for the state X 1 Σ g + for C 2 , X 4 Σ g − and 4 Π u for C 2 + and X 2 Σ g + for C 2 − . It may clarify the ground state of C 2 + , which should be X 4 Σ g − , but not 2 Π u .
