Abstract

Crystallized and fluorinated nanoporous Ta₂O₅ spheres were prepared by a combination of co-precipitation and hydrothermal methods in a NH₄F-containing water solution. The as-prepared porous spheres, with a pore-size of around 7 nm and a large specific surface area of 132 m² g⁻¹, show superior photocatalytic hydrogen production activity over P25 and commercial-Ta₂O₅.
