In our recent work we have studied formation of nanostructured cerium oxides from the choline chloride:urea deep eutectic solvent (DES). We found that the nanostructure of the ceria formed in this system is influcened strongly by the water content; changing from nanospherical to rod-like and the performance of this material in catalysis improves dramatically, alongside an increase in the microporosity of the material. Our previous experiments at room temperature demonstrate that there is a degree of solvent pre-structuring that causes reactive molecules (ie. cerium, water and urea) to show significant close-range ordering. Here we would like to determine whether or not this ordering is maintained at high temperature (relevant to synthesis), or whether domain formation in the DES is temperature dependent and also to follow the kinetics of ceria particle growth at several water contents.
