A synthetic route to indium(0) nanoparticles via an electrochemical reduction of haloindate(III) ionic liquids to indium(I), and its subsequent disproportionation to indium(0) and indium(III) in the bulk electrolyte, is described. In this sustainable method, the ionic liquid acts simultaneously as metal source, templating agent, and stabilising agent, with the electron as the only reducing agent. The nature of the ionic liquid cation is demonstrated to strongly affect the morphology and size distribution of the indium(0) nanoparticles.
