NOVELTY - Preparing reduced glutathione photoelectrochemical sensor involves preparing a reduced graphene oxide/titanium oxide composites (RGO/M-TiO2) composite functional layer on an indium tin oxide (ITO) conductive glass substrate. The zinc oxide nanorods grown on the surface of the substrate covered with the RGO/M-TiO2composite functional layer, and prepared a reduced glutathione photoelectrochemical sensor of a three-electrode system. USE - Method for preparing reduced glutathione photoelectrochemical sensor. ADVANTAGE - The preparation method of the reduced glutathione photoelectrochemical sensor is simple in process and low in cost, and only needs to spin a layer of composite functional layer on the substrate for growing zinc oxide, and simultaneously promotes the growth of ZnO nanorod electrode material and the separation of photogenerated carriers, and improves the photoelectric conversion efficiency of the device, and detection performance of the reduced glutathione (GSH) zinc oxide photoelectrochemical sensor is significantly improved.
