A bimetallic heterostructure has been shown effective to enhance the multi-carbon (C2+) product selectivity in CO2electroreduction. Clarifying the interfacial structure under electrolysis and its decisive role in the pathway selection are crucial, yet challenging. Here, we conceive a well-defined Ag-Cu...
High-rate production of multicarbon chemicals via the electrochemical CO2 reduction can be achieved by efficient CO2 mass transport. A key challenge for C−C coupling in high-current-density CO2 reduction is how to promote *CO formation and dimerizatio
strain in Cu nanocrystals by using the appropriate precursor and explains the difference in CO2RR activity relative to hydrogen evolution among the three derived Cu catalysts. Therefore, lattice strain has been identified as another factor promoting the CO2RR activity of derived Cu catalysts in additio...
Additionally, sets of Cyclic Voltammetry (CV) are performed between –3 and 3 V (vs. Ag/AgCl) at a scan rate of 100 mV s−1 to estimate the bandgap of the photoanode surfaces electrochemically. The estimated bandgap is calculated as the difference between the onset oxidation ...
. Given the fact that the tg-e2gsplitting stems from the energy difference between Ti 3d-orbitals with different geometric orientations, it is sensitive to the valence of Ti and the presence of point defects in titania35. Therefore, the above result suggests a low-valent Ti(III)- and [O...
There would be a noticeable difference. Extrapolate that notion to variability that can occur to the entire Earth's surface topography and atmosphere. Big changes in the topography and atmosphere could conceivably make (over the course of time) the steady state temperature of the Earth to change....
6). Given the fact that the tg-e2g splitting stems from the energy difference between Ti 3d-orbitals with different geometric orientations, it is sensitive to the valence of Ti and the presence of point defects in titania35. Therefore, the above result suggests a low-valent Ti(III)- and...
and BTOPAu, respectively (Supplementary Table1). BET results indicated that the specific surface areas of BTOAu3and BTOPAu were 11.74 m2/g and 12.25 m2/g, respectively. The Au coverage was determined to assess the performance difference of the photocatalysts with the following formula:...
(H2) and oxygen (O2), two flame ionization detectors (FID) were used to quantify methane (CH4)/carbon monoxide (CO), and ethane (C2H6)/ethylene (C2H4)/ethyne (C2H2), respectively. The reactors were connected with an online GC with a mass flowmeter at the outlet line. This flowmeter ...
difference in coordination numbers between the studied sample and reference sample, and the denominator is the coordination number for the normal reference sample. Therefore, the RCdfor our Ag-D catalyst is (12.0 − 7.2)/12.0 = 40%, while for the Ag foil reference, this value ...
