a In situ time-resolved PDFs G(r) for the CoO synthesis. The heating step includes heating from room temperature to 60 °C, 5 min at 60 °C, and heating from 60 to 160 °C. We set t0 (beginning of reaction time) to the point when we start heating to 160 °C. b Region of a illustrating the short-range order before the crystallization of CoO. c Zoom into the local order region of the PDFs for selected reaction times of the in situ data. Dashed lines show the first coordination shells of CoO. d Changes in the shortest Co–O bond over the reaction course, which indicate three reaction stages. e Structural models for the proposed reaction stages. The structures were obtained from the crystallographic data from references63,74,75 using the VESTA software76.
