研究目的
Investigating the therapeutic effects of a specific herbal medicine on a particular disease.
研究成果
The MWCNT/BiPO4/BiOI heterostructure composite PEC sensor demonstrated excellent performance for SA detection, including a low detection limit, wide linear range, and good stability, suggesting its potential for practical applications.
研究不足
The study focuses on the detection of SA under specific conditions and may require optimization for broader applications.
1：Experimental Design and Method Selection:
Hydrothermal methods were used to synthesize BiOI, BiPO4, BiPO4/BiOI (M), and MWCNT/BiPO4/BiOI (MWCNT/M) heterostructures for fabricating a PEC sensor for SA detection.
2：Sample Selection and Data Sources:
The synthesized materials were characterized using SEM and TEM.
3：List of Experimental Equipment and Materials:
SEM, TEM, XRD, XPS, UV–vis spectrophotometer, and electrochemical workstation were used.
4：Experimental Procedures and Operational Workflow:
The PEC sensor's performance was evaluated under visible light excitation in
5：1 M PBS. Data Analysis Methods:
The photocurrent response and electrochemical impedance spectroscopy (EIS) were analyzed to assess the sensor's performance.
