Research Abstract

Anion-lattice manipulation is one such effective approaches for developing the structural and physical properties of transition metal oxides. In my study, highly reduced nanostructured titania, novel layered Co and Fe oxyfluoride materials have been successfully obtained using low-temperature reactions and high-pressure synthesis.
