As a result, it shows an unexpectedly higher turnover frequency (435h) than that of Cu-N(190h), Cu-N(90h) and Cu nanoparticle (58h) catalysts, respectively. This work provides a facile and efficient method for regulating the electron configuration of single-atom catalyst and generates a ...
The electronic structures of the chalcopyrite-type CuFeS2 and CuAl0.9Fe0.1S2 are studied by x-ray photoemission (XPS), resonance photoemission, Auger-electron, optical reflectance, and electron-energy-loss (EELS) spectroscopies. The Fe 3d-derived states are revealed by the valence-band XPS spectr...

Diatomic molecule of copper. An all-electron ab initio self-consistent-field—configuration-interaction study of Cu 2 A theoretical study, at three levels of approximation [self-consistent field (SCF), multiconfiguration (MC)-SCF, and extensive configuration interaction CI... G del Conde - 《Phys...
This has motivated recent investigations of LaNiO3-based heterostructures and planar-trilayer nickelates that have been designed to imitate the electronic configuration of cuprates in pursuit of potential high TC superconductivity and other intriguing cuprate-related phenomena3, 8,9,10,11. Unlike the ...
Following the Aufbau diagram, this would be Following the Aufbau diagram, this would be the electron configuration for Cr and Cu: the electron configuration for Cr and Cu: This is the correct electron configuration: This is the correct electron configuration:...
The effective construction of electron transport channels has essential significance for electron-transfer rate enhancement in REDOX processes during peroxymonosulfate (PMS) activation. This study focuses on the establishment of Cu-involved covalent bonds due to the unique electron configuration of Cu ions...
Single-atom catalysts offer maximal atom utilization efficiencies and high-electronegativity heteroatoms play a crucial role in coordinating reactive single metal atoms to prevent agglomeration. However, these strong coordination bonds withdraw electron
• Hund's rule: The lowest energy e - configuration (called the ground state configuration), is the one with e - unpaired as long as possible and the electron spin maximized • Exceptions: Common ones: Cr, Mo and Cu, Ag, Au because half-filled and filled subshells are more stable ...
