Single-atom cobalt、Nanozyme、Biocatalysis、Uric acid、Molecular interactionA single-atom catalyst of A–Co–NG is explored for electrochemical uric acid (UA) detection for the first time and realize practical UA monitoring in serum samples.The A–Co–NG sensor demonstrates high performance for UA ...
Herein, we propose a new structure that cobalt atomically dispersed on BP nanosheets (BP〤o), and apply it as cocatalyst for photocatalytic H2 evolution and CO2 reduction under visible light (>420 nm) irradiation. Both scanning transmission electron microscope and X‐ray absorption near edge ...
Herein, we report the procedure for making single-atom cobalt (Co) array covalently bound onto distorted 1T MoS2nanosheets (denoted as SA Co-D 1T MoS2) via Co-S bonds through electrochemical cyclic voltammetry (CV) leaching of Co nanodisks (NDs)-MoS2nanosheet hybrids. The strain induced by l...
This work investigated the effects of co-adsorbates on the oxygen reduction activity of GDY-supported single-atom catalysts(SACs). We found that the co-adsorbates pull electrons from the metal atom and downshift its d-band center, which weakens the binding of the intermediates. Strong-binding Co...
(HER), which is critical to industrial water–alkali electrolysers, remains elusive and is a field of intense research. Here, by virtue of operando X-ray absorption spectroscopy on a uniform cobalt single-site catalyst, we report the atomic-level identification of the dynamic structure of ...
The single cobalt atoms build strong interactions with Ti3C2Tx by forming metal-oxygen/carbon bonds, resulting in the formation of the Co-Ti3C2Tx ensemble. As a result, the production rate of CO reaches a high value of 6.06 mmol h−1 g−1 over the optimal Co-Ti3C2Tx, which markedly...

Taking the single-atom cobalt (Co) array modified 2D MoS2 as an example (Figure 2), firstly 2D MoS2 and Co nanodisks (NDs) are synthesized using standard solvothermal procedures and standard air-free procedures, respectively. Then, the combination of Co NDs and 2D MoS2 is realized via an ...
