説明
Photocatalytic water splitting into H 2 and O 2 over various tantalates was reviewed and factors affecting photocatalytic activities of tantalates were discussed from a viewpoint of the crystal structure and the energy structure. Many tantalates, K 3 Ta 3 Si 2 O 13 , alkali and alkaline earth tantalates, were highly active photocatalysts for water splitting. The high activities were mainly due to the high conduction band level consisting of Ta5d orbitals. NiO-loaded NaTaO 3 with the distorted perovskite structure showed the highest activity among tantalates. Moreover, the activity of the NiO/NaTaO 3 photocatalyst was remarkably improved by doping of lanthanoids. The apparent quantum yield of NiO/NaTaO 3 doped with lanthanum was ca. 50% at 270 nm.
