Abstract

A polymerized complex (PC) technique was utilized to prepare high-purity barium tetratitanate (BaTi₄O₉) fine powders at a low temperature (700 °C). BaTi₄O₉ via the PC route, combined with RuO₂, exhibited 2.4 times larger photocatalytic activities for the decomposition of water compared to those for a sample prepared by a solid-state reaction method. A considerably large surface area (∼30 m²/g) of the BaTi₄O₉/RuO₂ powder via the PC route, when compared with ∼5 m²/g for the solid-state reaction powder, was supposed to be one of the key factors responsible for the high photocatalytic activity observed.
