研究目的
Investigating the fabrication and photocatalytic performance of raspberry-shaped reduced graphene oxide labelled Fe/CeO2 ternary heterojunction for the degradation of Congo red dye under UV light.
研究成果
The raspberry-shaped Fe-CeO2/RGO ternary nanocomposite exhibits excellent photocatalytic performance for the degradation of Congo red under UV light, attributed to the synergistic effect between RGO sheets and the redox system of Ce and Fe. The material shows good reusability and stability, suggesting potential for environmental remediation applications.
研究不足
The study focuses on UV light irradiation for photocatalytic degradation, and the performance under visible light or other conditions was not explored. The scalability and cost-effectiveness of the synthesis method for large-scale applications were not addressed.
1：Experimental Design and Method Selection:
The ternary photocatalyst was synthesized via a simple hydrothermal method. Structural, morphological, elemental composition, and optical properties were characterized using XRD, FESEM, TEM, EDX, PL, and UV–visible spectroscopy.
2：Sample Selection and Data Sources:
Analytical grade cerium nitrate hexahydrate and iron(III) nitrate nonahydrate were used as precursors. Graphite powder was procured for graphene oxide synthesis.
3：List of Experimental Equipment and Materials:
Hydrothermal autoclave, UV-1800 spectrophotometer, Brucker D8 advance powder diffractometer, FESEM, TEM, EDX, PL spectrometer.
4：Experimental Procedures and Operational Workflow:
Synthesis involved hydrothermal treatment of precursors with RGO at 180°C. Photocatalytic degradation of Congo red was performed under UV light.
5：Data Analysis Methods:
Photocatalytic efficiency was determined by measuring the degradation percentage of Congo red using UV–visible spectroscopy.
