Mesoporous Tantalum Oxide Photocatalyst: Structure and

Jan 11, · Mesoporous nanostructured pure tantalum pentoxide and Eudoped Ta 2 O 5 were produced by facile and reproducible onepot procedure not involving structure directing agents. The asproduced material is poorly crystalline and catalytically inactive. Photoluminescence behavior of the doped oxide indicates that it is formed by quick nucleation of pure Ta 2 O 5, leaving the Eudopant .
