actants, ions, and electrons—all at catalytically active sites, is increasedfromthe submicrometer regime to the several micrometer length scale. We beganby modeling the available gaseous reactant in different gas-phase electrolysis scenarios (Fig. 1, E and F), building on pre- ...
This is usually systematically characterised by four CO2RR performance metrics: (1) faradaic efficiency (FE) is the ratio between the quantity of required electrons to generate one target product and the total Coulomb quantity, which can represent the selectivity towards a specific CO2-derived ...

Rate constant of electron-impact dissociation of CO2 in a direct-current atmospheric-pressure gas discharge is found based on detailed analysis and generalization of the results of calculations of the energy spectrum of electrons in gas discharges in pure carbon dioxide CO2 and CO2-containing mixtures...
Under light irradiation, electrons in the In2O3 and Nb2O5 VBs are initially excited to their respective CBs. Due to the bent energy bands, the IEF with the direction from Nb2O5 to In2O3, and the Coulomb attraction between electrons and holes, the photogenerated electrons in the In2O3...
Calculations have been made of transport coefficients of electrons in gas mixtures for ratios CO2:N2:He of 1:1:8, 1:2:3, 1:7:30, and 1:0.25:3. New cross sections for CO2derived from swarm experiments are used together with previously published cross sections for N2and He. Curves are ...
This inertness is the underlying reason why CO2 has broad industrial application as solvent (supercritical CO2), as fire and pest extinguisher, and as a non-toxic amusement additive in the food industry. From the standpoint of building a low-carbon economy, each potential use of CO2 ...
The amounts of energy expended by the electrons on different channels of inelastic molecular excitation and ionization are determined. The results are presented in a form convenient for the direct determination of electron-molecule interaction rates. 关键词: Boltzmann Transport Equation Carbon Dioxide ...
(Supplementary Figure12b)7. For Co-bCN, the signal intensities in different atmospheres decrease as the order of N2 > air > O2, as opposed to that for IL/bCN, where O2is found to impose a negative effect. This suggests that Co single atoms trap holes instead of electrons to ...
CO2 obtains electrons from photoexcited spiro-OMeTAD, rapidly promoting its p-type doping and resulting in the precipitation of carbonates. The CO2-treated interlayer exhibits approximately 100 times higher conductivity than a pristine film while realizing stable, high-efficiency perovskite solar cells ...
