研究目的
Investigating the photocatalytic effects of hierarchical core-shell tungsten oxide/TiO2 nanowires on the degradation of rhodamine B (RhB).
研究成果
WO3/TiO2 core-shell nanowires prepared by depositing a layer of TiO2 on the surface of WO3 nanowires have photocatalytic activity in the degradation of RhB, due to the charge separation effect between these two semiconductors. This indicates these core-shell nanowire arrays have good potential in wastewater treatment.
研究不足
The technical and application constraints of the experiments include the adjustment of TiO2 thickness by the number of laser pulses and the potential for optimization in the charge transformation between TiO2 nanoparticles.
1：Experimental Design and Method Selection:
WO3/TiO2 core-shell nanowires were prepared by depositing a layer of TiO2 nanoparticles on the surface of WO3 nanowires via a pulse laser deposition method.
2：Sample Selection and Data Sources:
WO3 nanowires were synthesized on silicon (100) wafer.
3：List of Experimental Equipment and Materials:
Field emission scanning electron microscopy (FESEM, FEI Inspect F50), X-ray diffraction (XRD, Smartlab, Rigaku), transmission electron microscopy (TEM, Tecnai G2-20), ultra–visible spectroscopy (UV–vis, ShimadzuUV2450).
4：0). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The photocatalytic activity was measured by the degradation of RhB under UV-light irradiation.
5：Data Analysis Methods:
The absorbance of the solution was measured by UV–vis spectroscopy to calculate the RhB concentration.
