A green synthesis of a layered titanate, potassium lithium titanate; Lower temperature solid-state reaction and improved materials performance

A layered titanate, potassium lithium titanate, with the size range from 0.1 to 30 μm was prepared to show the effects of the particle size on the materials performance. The potassium lithium titanate was prepared by solid-state reaction as reported previously, where the reaction temperature was varied. The reported temperature for the titanate preparation was higher than 800 C, though 600 C is good enough to obtain single-phase potassium lithium titanate. The lower temperature synthesis is cost effective and the product exhibit better performance as photocatalysts due to surface reactivity.
