Biotemplating of barium titanate in deep eutectic solvent synthesis Dr Jessica Andrews , Connagh Launcbury, Dr Rebecca Boston Department of Materials Science and Engineering, Sir Robert Hadfield Building, Mappin Street, University of Sheffield, Sheffield, S1 3JD, UK The reduction of energy consumption in functional oxide manufacturing is an increasingly important area of research. Synthetic routes utilising deep eutectic solvents require much lower processing temperatures compared to conventional solid state synthesis and are a promising method in the production of nano-scale materials [1-3] . Biotemplating to control morphology of functional oxides can enable manipulation and enhancement of properties and has been demonstrated in ionic liquid synthesis [4-5] . This work aims to tailor the morphology of barium titanate by incorporating sodium alginate as a biotemplate into a deep eutectic solvent made of malonic acid and choline chloride. The effects of template concentration and calcination temperature on the resulting powders are investigated. References 1. Boston, R.; Foeller, P. Y.; Sinclair, D. C.; Reaney, I. M.
