Preparation of K₂La₂Ti₃O₁₀ by Polymerized Complex Method and Photocatalytic Decomposition of Water

Abstract

A polymerized complex (PC) technique was applied to the preparation of a highly active photocatalyst, K2La2Ti3O10, with a layered perovskite type structure to decompose H2O into H2 and O2. The catalyst prepared by the PC technique had a higher photocatalytic activity than that prepared by conventional solid-state reaction method.
