| dc.description | The authors wish to thank Dr. R. Kalendarev for the synthesis of ZnO2 sample. A.K. would like to thank the financial support of the ERDF Project No. 1.1.1.1/20/A/060. The experiment at the MAX IV synchrotron was performed within the project 20190823. Institute of Solid State Physics, University of Latvia as the Center of Excellence has received funding from the European Union's Horizon 2020 Framework Programme H2020-WIDESPREAD-01-2016-2017-TeamingPhase2 under grant agreement No. 739508, project CAMART2. | en_US |
| dc.description.abstract | The Zn K-edge X-ray absorption spectroscopy is used to investigate in situ the decomposition of zinc peroxide ((Formula presented.)) to zinc oxide (ZnO). Principal component and linear combination analyses of the extended X-ray absorption fine structure (EXAFS) spectra are employed to identify the phase composition of the oxide upon heating to 900 °C. Only the (Formula presented.) phase is found up to 180 °C, whereas only the nanocrystalline ZnO phase is occurring above 250 °C. Detailed structural information on the temperature dependence of the local environment of zinc atoms is obtained using the reverse Monte Carlo (RMC) simulations. A strong increase of disorder is found upon approaching the decomposition temperature, evidenced by the broadening of Zn–O and Zn–Zn pair distribution functions (PDFs) and related mean-square relative displacements. © 2022 Wiley-VCH GmbH. | en_US |
