Research Abstract

Inorganic synthesis was carried out using immiscible liquid-liquid biphasic systems under ambient pressure at moderate temperatures. Hybrid materials intercalated with organic acid ions were obtained for hydroxide compounds including transition metal or rare-earth metal elements. By dissolving different metal ions in organic and aqueous solutions, complex metal oxides could be formed through reactions at the liquid-liquid interface. Various materials thus obtained were evaluated as functional materials such as phosphors and electrodes of dye-sensitized solar cells.
