研究目的
To synthesize coral-like CuO dendrites with enhanced photocatalytic performance for the degradation of methylene blue (MB) under visible light irradiation.
研究成果
The coral-like CuO dendrites synthesized via a simple solvothermal method exhibited enhanced photocatalytic performance, degrading over 98% of MB in 60 min under visible light irradiation with excellent stability and reusability.
研究不足
The study focuses on the synthesis and photocatalytic performance of coral-like CuO dendrites under specific conditions. The scalability of the synthesis method and the performance under different environmental conditions were not explored.
1：Experimental Design and Method Selection:
A solvothermal method was used in the mixed solvent of distilled water and ethanol with assistance of DTAB to synthesize coral-like CuO dendrites.
2：Sample Selection and Data Sources:
The products were characterized by XRD, FESEM, EDX, TEM, XPS, and BET analysis techniques.
3：List of Experimental Equipment and Materials:
X-ray diffractometer (Shimadzu XRD-6100), field emission scanning electron microscope (FESEM, JSM-6700F), transmission electron microscope (TEM, Talos F200X), X-ray photoelectron spectrometer (XPS, ESCALAB 250Xi), UV-visible spectrophotometer (Hitachi U-3310).
4：0). Experimental Procedures and Operational Workflow:
4. Experimental Procedures and Operational Workflow: The synthesis involved mixing Na2CO3 and Cu(CH3COO)2 in a water-ethanol solvent with DTAB, heating in an autoclave at 180°C for 24 h, followed by centrifugation, washing, and drying.
5：Data Analysis Methods:
The photocatalytic activity was evaluated by degrading MB under visible light irradiation, with the degradation rate calculated using UV-Vis spectrophotometry.
