| Abstract |
The interface has a synergetic effect in catalytic reactions. Metal oxides such as MgO and CeO2 are active catalysts in CO oxidation; however, there are limitations in their activity. We assume the co...mbined interface of MgO and CeO2 can be integrated to produce a better active catalyst. Although there is a 28% lattice mismatch between MgO-CeO2, we have successfully deposited CeO2 nanoparticles on MgO nanowires by the VLS method using the PLD technique. Here for the first time we show the images of the deposited nanoparticles obtained by SEM and EDS accompanied with their equivalent Photo-luminescence graphs. The paper discusses in depth how the interface between decorated MgO-nanowires with CeO2- nanoparticles started nuclei and how temperature and oxygen partial pressure affected their sizes. This work will serve as a base for future studies on other bimetal oxides interfacesshow more
