研究目的
Investigating the therapeutic effects of a specific herbal medicine on a particular disease.
研究成果
The study successfully developed a portable PEC sensor based on BiVO4/FTO for AA detection, demonstrating wide linear range, low detection limit, and high sensitivity. The sensor's practicality was enhanced by using a low-power LED light source and an ammeter for signal detection.
研究不足
The study is limited by the use of a specific light source (20 W LED lamp) and the need for further optimization of the sensor for broader applications.
1：Experimental Design and Method Selection:
The study involved the electrodeposition of BiOI on FTO, followed by transformation into BiVO4 through annealing. The BiVO4/FTO electrode was then used as a PEC sensor for AA detection under LED light illumination.
2：Sample Selection and Data Sources:
The samples included BiOI films electrodeposited on FTO and transformed into BiVO4 films. Data was collected using a CHI650E electrochemical workstation.
3：List of Experimental Equipment and Materials:
Equipment included a Rigaku diffractometer, SEM (CarlZeiss), UV-vis spectrophotometer (UV-2550, Daojin), and CHI650E electrochemical workstation. Materials included Bi(NO3)3?5H2O, KI, HNO3, and others.
4：Experimental Procedures and Operational Workflow:
The process involved electrodeposition of BiOI, transformation to BiVO4, and PEC performance testing under LED light.
5：Data Analysis Methods:
Data was analyzed using electrochemical impedance spectroscopy and amperometric response measurements.
