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.
