研究目的
To synthesize water soluble and fluorescent carbon quantum dots (CQDs) using human fingernails as a carbon precursor and to enhance the photocatalytic performance of g-C3N4 in the degradation of 2,4-dicholorophenol (2,4-DCP).
研究成果
The CQD doped g-C3N4 was successfully synthesized via a green and sustainable method, exhibiting enhanced catalytic activity with a degradation rate of 71.53% for 2,4-DCP under sunlight. The improvement was attributed to reduced electron-hole pairs recombination rate and increased light absorption range.
研究不足
The study focuses on the photocatalytic degradation of 2,4-DCP under sunlight, which may vary under different light conditions. The scalability and practical application of the method in industrial settings were not explored.
1：Experimental Design and Method Selection:
Hydrothermal method was used for synthesizing CQDs from human fingernails. The CQDs were then coupled with g-C3N4 to form nanocomposites.
2：Sample Selection and Data Sources:
Human fingernails and urea were used as precursors for CQDs and g-C3N4, respectively. 2,4-DCP served as the pollutant sample.
3：List of Experimental Equipment and Materials:
Autoclave, oven, centrifuge, vacuum oven, FESEM, EDX, UV-DRS, HPLC.
4：Experimental Procedures and Operational Workflow:
Synthesis of CQDs and g-C3N4, preparation of CQD/g-C3N4 composites, characterization, and photocatalysis under sunlight.
5：Data Analysis Methods:
Degradation rate was calculated based on the concentration of 2,4-DCP before and after photocatalysis.
