Silver Single‐Atom Catalyst for Efficient Electrochemical CO2 Reduction Synthesized from Thermal Transformation and Surface Reconstruction
Abstract
We report an Ag 1 single‐atom catalyst (Ag 1/MnO 2), which was synthesized from thermal transformation of Ag nanoparticles (NPs) and surface reconstruction of MnO 2. The evolution process of Ag NPs to single atoms is firstly revealed by various techniques, including in situ ETEM, in situ XRD and DFT calculations. The temperature‐induced surface reconstruction process from the MnO 2 (211) to (310) lattice plane is critical to firmly confine the existing surface of Ag single atoms; that is, the thermal treatment and surface reconstruction of MnO 2 is the driving force for the formation of single Ag atoms. The as‐obtained Ag 1/MnO 2 achieved 95.7 % Faradic efficiency at −0.85 V vs. RHE, and coupled with long‐term stability for electrochemical CO 2 reduction reaction (CO 2 RR). DFT calculations indicated single Ag sites possessed high electronic density close to Fermi Level and could act exclusively as the active sites in the CO 2 RR. As a result, the Ag 1/MnO 2 catalyst demonstrated remarkable performance for the CO 2 RR, far surpassing the conventional Ag nanosized catalyst (Ag NP/MnO 2) and other reported Ag‐based catalysts.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
