In recent years, antibiotics (such as levofloxacin (LEV)) have been detected widely in the environment. Semiconductor photocatalysis has been recognized as a promising technology for removing pollutants in the environment. In this work, nitrogen and carbon codoped titanium dioxide nano-catalyst (NCD-TiO2) was immobilized in polyvinyl alcohol (PVA) matrix to form PVA/NCD-TiO2 films through solution casting and thermal treatment, which exhibited good photocatalytic efficiency for LEV degradation. The results showed that about 42% LEV can be degraded after 2 h in the presence of PVA/NCD-TiO2 nanocomposite film (the weight ratio of NCD-TiO2 to PVA is 8% and thermal treatment is 120 °C) under visible light. Moreover, possible pathways of photocatalytic degradation of LEV according to the detected intermediates are proposed, which provide insight into the degradation mechanism of LEV by using PVA/NCD-TiO2 photocatalytic films. Finally, the synthesized PVA/NCD-TiO2 films exhibited excellent reusability and stability in photocatalysis. This work provides fundamental support for the design of a high-stability, excellent photocatalyst for practical application.

The optical and electrical properties of sodium niobate crystals and ceramics doped with Mn atoms are studied. Na(Nb1−zMnz)O3 crystals exhibit actual z = 0–1.0 wt% Mn content. The Na(Nb1−zMnz)O3 ceramics contains Mn from the 0–5 wt% range. The (Na1−xBix)(Nb1−yMny)O3 ceramics is codoped with x = 0.015–0.50 and y = 0.01–0.33. Mn addition decreases the reflectance magnitude. Combined nonstoichiometry and local disorder in the crystal lattice, resulting from Mn doping and oxygen vacancies, induce contributions to the electronic structure. The visible and near‐infrared (Vis–NIR) diffuse reflectance, R(λ), spectra include a linear combination of contributions. The modified Kubelka–Munk function representation allows estimation of the optical energy gap, Egap. This estimation is qualitative because of the complex structure of the samples. Two optical gaps, showing dependence on Mn content, are discerned when Mn content <1 wt%. Egap,high changes toward the Shockley–Queisser limit, from 1.85 to 1.4 eV, when Mn content is low (z < 1 wt%). Simultaneous occurrence of Egap,low of 1.0–1.3 eV suggests tuning possibility. Egap of ≈1 eV dominates optical properties when Mn content is >1 wt%. The optical features are consistent with activation energy attributed to thermally generated electrical conductivity.
