Single-atom Fe-N-C catalysts are considered a candidate to replace the platinum group metals in oxygen reduction reaction (ORR), due to its high activity, anti-toxicity, and metal atom utilization1,2,3,4. Advanced Fe-N-C materials show comparable ORR performance to that of benchmark Pt/C3...
spectra of Cu K-edge in 2D-Cu–N–C, 2D-FeCu–N–C, and FePc@2D-Cu–N–C display a main peak at ~1.5 Å (not corrected for phase shift) due to the Cu–N coordination (Fig.3c). All wavelet transform (WT) contour plots at the Fe/Cu K-edge of 2D-FeCu–N–C, and F...
Single-atom cooling by superfluid immersion: A nondestructive method for qubits We present a scheme to cool the motional state of neutral atoms confined in sites of an optical lattice by immersing the system in a superfluid. The motion... AJ Daley,PO Fedichev,P Zoller - 《Physical Review A...
Herein, we constructed FeN4 structures on a carbon nanotube (CNT) to obtain single-atom catalysts (FeSA-N-CNT) to generate RFeS in the presence of peroxymonosulfate (PMS). The obtained FeSA-N-CNT/PMS system exhibited outstanding and selective reactivity for oxidizing EOCs over a wide pH ...
We propose the great potential of single atom catalysts (SACs) for CO2electroreduction with high activity and selectivity predictions over a competitive H2evolution reaction. We find the lack of an atomic ensemble for adsorbate binding and unique electronic structure of the single atom catalysts play ...
A series of carbon-based binary single-atom catalysts of Fe and Ni coordinated by nitrogen are fabricated using a glucose-chelating method. Depending on the Ni/Fe content, they exhibit a wide-range of controllable CO/H2 ratio from 0.14 to 10.86, which is meaningful to specific chemical process...
