用共振光电子能谱研究了钴基析氧催化剂（Co-PI，PI =从pH 7磷酸盐中电沉积而成）的Co L3和O 1 s边。对于单个Co 3d态，我们确定它们的构型、自旋和相对于费米能的能级。我们确定了钴的二价高自旋态和三价低自旋态。此外，我们还发现了相应的氧-金属电荷转移态。我们认为三价电荷转移态是析氧反应的活性态。
Cobalt based oxygen evolution catalysts (Co-PI, PI = electrodeposited from pH 7 phosphate) are studied by resonant photoemission spectroscopy at the Co L3 and O1s edge. For the individual Co3d states, we determine their configuration, their spin, and their energy level relative to the Fermi energy. We identify the Co divalent high spin state and the trivalent low spin state. In addition, we also find the corresponding oxygen-to-metal charge transfer states. We attribute the trivalent charge transfer state to be the active state for the oxygen evolution reaction.
