Electron transfer catalysis
WebIn electron transfer events, at least two metal species undergo a redox process and change their oxidation state – alongside their properties and reactivity. In comproportionation reactions, two cations with different oxidation states converge into a unique, intermediate species, whereas the reverse happens in disproportionation reactions. WebA deficit-spending model for electron transfer has recently been proposed that incorporates protein conformational gating that favors uni-directional electron transfer among the …
