Preparation method of photoelectrochemical sensor for detecting tetracycline hydrochloride

The invention belongs to the technical field of tetracycline hydrochloride detection by a photoelectrochemical sensor, and discloses a preparation method of a novel material photoelectrochemical sensor and detection application of the novel material photoelectrochemical sensor to tetracycline hydrochloride. The preparation method comprises the following steps: preparing a Bi2Te2. 85Se0. 15 nano material through simple hydrothermal synthesis, centrifuging the obtained material, washing, drying and the like, and enabling the material to be stably attached to ITO (Indium Tin Oxide) conductive glass, so as to obtain the photoelectrochemical sensor. Corresponding photocurrent change rate curves can be obtained by placing the prepared photoelectrochemical sensor under tetracycline hydrochloride with different concentrations, corresponding results can be obtained through a good linear relation, meanwhile, the performance difference between different batches of sensors is very low, the photoelectrochemical sensor can
