Description
Summary:The hydrolysis of H 2 TaF 7 when it slowly forms via etching Ta powders with HF and H 2 O 2 under hydrothermal conditions produces hierarchical nanostructures of fluorinated and naked Ta 2 O 5 single-crystalline nanorods, which exhibit a far greater photocatalytic activity for H 2 production than commercial Ta 2 O 5 particles. The hydrolysis of H 2 TaF 7 under hydrothermal conditions produces hierarchical nanostructures of fluorinated and naked Ta 2 O 5 single-crystalline nanorods, which exhibit excellent photocatalytic activity for H 2 .
