Summary This work presents a Cu single-atom catalyst (SAC)-catalyzed Sonogashira coupling reaction of lodine benzene and phenylacetylene to manufacture diphenylacetylene, with a satisfactory yield employing Cu
Single-atom catalysts anchoring offers a desirable pathway for efficiency maximization and cost-saving for photocatalytic hydrogen evolution. However, the single-atoms loading amount is always within 0.5% in most of the reported due to the agglomeration at higher loading concentrations. In this work, ...
still distributed in a single-atom state. The Cu–O coordination number slightly decreased to 2.56 during the reaction, accompanied by a slight decrease in the valence state. Meanwhile, the Cu–O bond became slightly longer under the reaction conditions (increasing from 1.92 to 2.05 Å; Su...
Herein, we introduce single-atom Cu anchored on N-doped graphene (Cu-NG) as a cocatalyst coupled with carbon nitride via covalent bonding to enhance photocatalytic H2O2 production. The Cu-NG/carbon nitride could broaden the light absorption from UV to near-infrared region, contributing to the ...
The synchrotron radiation-based X-ray absorption fine structure spectroscopy (XAFS) results reveal the atomic structure and coordination state of the single-atom Cu and Co species in n-Cu/BP and n-Co/BP. The Cu K edge X-ray absorption near-edge structure (XANES) spectrum of n-Cu/BP compa...
Co3O4/Cu1-N-C catalyst was synthesized by adding sodium borohydride to the mixture containing Cu single-atom catalysts and cobalt nitrate. Cu single atoms dispersed on N-doped carbon (denoted as Cu1-N-C) were prepared via pyrolyzing Cu-doped ZIF-8 at 900 °C under Ar atmosphere (Su...
此外,本文还提出了EMSI在SACs上的挑战、机遇和未来的发展,以提供一个整体的观点和对后续研究的参考。相关工作以《Electronic Metal–Support Interaction of Single‐Atom Catalysts and Applications in Electrocatalysis》为题在《Advanced Materials》上发表综述。
If the substitution of Cu for Hg and excess O at (1200) are coupled, then the effect is to insert a perovskite-like six-coordinated copper site at (000). No evidence was found for a split atom at the barium sites in these compounds. 展开 ...
tyrosine and cytosine. The single-atom sites on a chip strategy can also be applied in a portable Raman platform with high sensitivity comparable to that on a benchtop instrument, which can be readily extended to point-of-care testing or in-vitro detection of various biomolecules (see the arti...
atom decreases from −2.59e for the 2nd nearest to −2.34e for the nearest, suggesting a lowering of the valence of the nearest Wδ+(δ < 6), induced by the oxygen vacancy. Such reduced oxidation states of W around the defect were also the case for the Cu-def-WO3, which ...
