研究目的
Investigating the fabrication of carbon quantum dots (CQDs) from orange waste peels via a hydrothermal method for antimicrobial applications.
研究成果
The CQDs derived from orange waste peels show promising antibacterial activity, especially against gram-negative bacteria, and have potential applications in optoelectronic devices and biomedical fields.
研究不足
The study focuses on the antibacterial activity of CQDs against specific bacterial strains and does not explore other potential applications or the mechanism of antibacterial action in depth.
1：Experimental Design and Method Selection:
The CQDs were synthesized using a simple hydrothermal method with orange waste peels as the carbon source.
2：Sample Selection and Data Sources:
Orange waste peels and citric acid were used as starting materials.
3：List of Experimental Equipment and Materials:
Te?on-lined stainless-steel autoclave, deionized water, ammonia solution.
4：Experimental Procedures and Operational Workflow:
The solution was transferred into an autoclave at 200°C for 6 h. The antibacterial assay was performed using the disc diffusion method.
5：Data Analysis Methods:
UV–vis absorption spectrum analysis and Tauc’s plot were used to calculate the optical energy bandgap.
