The paper entitled "Deep eutectic-solvothermal synthesis of nanostructured ceria" published in Nature Communications (DOI: 10.1038/ncomms14150) by Dr Laura Torrente has been highlighted in the ISIS Neutron and Muon Source 2017 Annual review as a breakthrough for the design of a new class of economic and eco-friendly solvents for the synthesis of nanostructured materials.

Deep Eutectic Solvents (DESs) are part of an extended class of ionic liquids. Often made from cheap and safe components, they have the potential to be used as designer solvents, with none of the inherent toxicity of many room temperature ionic solvents. This study details work carried out on SANDALS, using wide Q-range liquid phase neutron diffraction to investigate the synthesis of nanostructured ceria using the DES reline.

We elucidated the mechanism of synthesis at a molecular scale where the reline solvent plays the role of a latent supramolecular catalysts where the increase in reaction rate from solvent-driven pre-organization of the reactants is most significant.

Ceria is a technologically-important material, used in catalysis, emissions control and solid oxide fuel cells. The new understanding this work has given us of deep eutectic-solvothermal methodology will enable future developments in low-temperature synthesis of nanostructured ceria and other oxides, facilitating their manufacture with economic, eco-friendly and non-toxic solvents.
