Abstract

A fine powder of sodium tantalum(V) trioxide as single-phase perovskite NaTaO₃ has been successfully prepared by hydrothermal synthesis through the reaction of a sodium hydroxide solution and ditantalum pentaoxide powder at low temperature (373-473 K). The NaTaO₃ powder has high photocatalytic activity for both H₂ evolution (8.0 mmol h ^-1) and O₂ evolution (4.1 mmol h^-1), which is attributed to the high surface area, small particle size and high crystallinity of the powder catalyst.
