Abstract
In this paper we show how the formation of zinc oxide from zinc peroxide takes place during thermal decomposition, through a combination of X-ray Absorption Spectroscopy (XAS) and X-ray Diffraction (XRD). The time-resolved study allowed us to follow the changes in both the local structure of the material, in particular the conversion of octahedral Zn-O coordination to tetrahedral one through EXAFS and XANES analysis and at the same time the particle growth using both EXAFS and diffraction. Multi-cluster analysis provided information on the phase changes which could be cross-correlated with diffraction results which suggests an abrupt change in the long range coordination followed by a slow growth of zinc oxide NPs. This study allowed us to gain a detailed understanding of zinc peroxide decomposition leading to the formation of zinc oxide.
