Abstract

The invention relates to the technical field of analysis and detection, and discloses a wireless photoelectrochemical indirect analysis and detection device and a manufacturing method thereof. According to the device, a first control electrode is located in a first electrolyte in a first electrolytic tank; a second control electrode is located in a second electrolyte in a second electrolytic tank;a closed bipolar electrode is composed of a conductor, a detection electrode and a photoelectrode loaded with a photoelectric semiconductor material; the detection electrode and the photoelectrode are positioned in the first electrolytic tank and the second electrolytic tank respectively; the first electrolytic tank is connected with the second electrolytic tank through the conductor; a light source is fixed above the photoelectrode; a to-be-detected substance is contained in the first electrolyte; a stabilizer is contained in the second electrolyte; an electrochemical workstation is connected with the first control electrode and the second control electrode through wires; and potential control is carried out on the detection electrode and the photoelectrode. A bipolar electrode technology is utilized for the first time, and the remote detection of a target object is realized on the basis of the principles of charge conservation and limited current.

Description

technical field [0001] The invention relates to the technical field of analysis and detection, in particular to a wireless photoelectrochemical indirect analysis and detection device and a manufacturing method thereof. Background technique [0002] In recent years, the analysis and testing technology based on photoelectrochemistry has made great progress, and its application range is more and more extensive. Photoelectric analysis has a series of advantages such as simple equipment, easy operation, and high sensitivity. At present, the basic strategy of photoelectric analysis is to modify the electrode surface of photoelectric active materials by irradiation of specific wavelengths of light. During this process, there will be mutual conversion between electrical energy, chemical energy and light energy, and electron transfer will occur between the detection object and the photoelectric semiconductor material. Thereby, a photocurrent is generated, and the detection of the ta...
