Fig. 7: Thermochemical frameworks for I-PCET.
From: Proton-coupled electron transfer controls peroxide activation initiated by a solid-water interface
The PTET and ETPT pathways are situated in the upper and lower sections, respectively. The pathway bisecting the diagram is CPET, in which electrons and protons are transferred without the formation of intermediates. Note that schematic diagrams of the transition states of the interfacial reaction have been positioned at the corresponding angles on the circles (i.e., at 0°, 90°, 180°, and 270°).
