研究目的
To synthesize faceted TiO2 with dominant {010} facets for the photocatalytic degradation of acetaminophen (ACE) in an aqueous solution and study the type of generated oxygen vacancy in faceted-TiO2.
研究成果
The {010} anatase TiO2 facets were successfully synthesized and showed good photocatalytic activity and reusability. NaBH4 reduction induced different types of Ti3+ species in P25 and T-{010}, affecting their photocatalytic performance under visible light. The study demonstrates the potential of faceted-TiO2 for practical applications in water treatment.
研究不足
The study focuses on the photocatalytic degradation of ACE and may not be directly applicable to other pollutants. The synthesis process requires specific conditions and materials.
1：Experimental Design and Method Selection:
A two-step hydrothermal reaction was used to synthesize faceted TiO2 with dominant {010} facets. A solid-state chemical reduction approach (NaBH4) at a mild temperature (300 ?C) was utilized for the generation of oxygen vacancies.
2：Sample Selection and Data Sources:
P25 (commercial TiO2) and synthesized T-{010} were used as samples.
3：List of Experimental Equipment and Materials:
Te?on-lined stainless steel autoclave, UV-vis spectrophotometer, electron paramagnetic resonance (EPR) spectrometer, etc.
4：Experimental Procedures and Operational Workflow:
Hydrothermal synthesis, NaBH4 reduction, photocatalytic degradation experiments under UV and visible light, sedimentation studies.
5：Data Analysis Methods:
Langmuir-Hinschelwood model for kinetic analysis, UV-vis absorption spectra for band gap calculation, EPR for oxygen vacancy concentration analysis.
