Notes:
Tantalum dioxide and nitrogen co-doped titanium dioxide nanopowders, denoted as(Ta2O5, N) co-doped TiO2, were fabricated by a high-energy ball miller using TiO2, Ta2O5 and ureaas raw materials. Experiments on the photocatalytic activities of the (Ta2O5, N) co-doped TiO2 werecarried out in the form of photodegradation of methylene blue (MB) in aqueous solution undervisible light irradiation. Enhanced photocatalytic activities were observed for the (Ta2O5, N)co-doped TiO2 than commercial Degussa P25. Besides, physical, chemical and optical properties,including XRD, DRS, and XPS were detected to analyze the origins for the enhanced photocatalyticactivities of the prepared samples
