    A single phase of Ba3Ta6Si4O26 consisting of one-dimensional TaO6 chains has been synthesized by an amorphous metal complex (AMC) method employing water soluble materials, tantalum peroxolactate and silicon tetrapropyleneglycoxide. In contrast, a polymerizable complex method of another solution process gave a mixed phase of Ba 3Ta6Si4O26 and orthorhombic BaTa2O6. It has been suggested that homogeneity of the precursors strongly affected the phase purity. Ba3Ta 6Si4O26 produced hydrogen and oxygen from water under ultraviolet irradiation. Thus, the present research revealed that Ba 3Ta6Si4O26 is an active photocatalyst for water splitting. Ba3Ta6Si 4O26 prepared by the AMC method showed higher activity than that prepared by a solid state reaction.
