Remediation of antibiotics by photocatalysis technique has been regarded as a promising route to tackle with the environmental pollution affecting human survival and development. In this work, brookite TiO2 nanorods with different oxygen vacancy have been synthesized through tailoring the volume of ethylene glycol by hydrothermally treatment with NaTiOx-nanoassembly. After constitute and morphology confirmation with different characterizations, their photocatalytic performances are evaluated via ciprofloxacin (CIP) antibiotic degradation experiments. The result shows that the TiO2-0 has the highest photocatalytic efficiency towards CIP degradation, comparing with TiO2-15 and TiO2-30 samples. Although the TiO2-30 has high concentration oxygen vacancy, it exhibits excellent adsorption ability in the dark, rather than CIP degradation rate. The photo/electrochemical tests suggest the photo-generated electron lifetime, charge transfer ability, and the effective active sites on the material’s surface are inversely proportional to the concentration of oxygen vacancies. It also concludes that rational fabrication conditions tailoring of the photocatalyst could optimize the corresponding capability in the antibiotic degradation process. In addition, the possible degradation pathway is also proposed based on the high resolution mass spectrometry (HRMS), and the acute toxicity changes in the degradation process are also predicted.
期刊介绍：
Catalysis Letters aim is the rapid publication of outstanding and high-impact original research articles in catalysis. The scope of the journal covers a broad range of topics in all fields of both applied and theoretical catalysis, including heterogeneous, homogeneous and biocatalysis.
The high-quality original research articles published in Catalysis Letters are subject to rigorous peer review. Accepted papers are published online first and subsequently in print issues. All contributions must include a graphical abstract. Manuscripts should be written in English and the responsibility lies with the authors to ensure that they are grammatically and linguistically correct. Authors for whom English is not the working language are encouraged to consider using a professional language-editing service before submitting their manuscripts.
