The cathodic protection technology is one of the main technologies for preventing metal corrosion, and in recent years, the photo-induced cathodic protection technology has become a research hotspot in the field of corrosion protection as a novel cathodic protection technology. The photo-induced cathodic protection is to utilize a semiconductor film to generate photoelectrons under the illumination of sunlight so as to provide enough electrons for protected metal and enable the potential of the protected metal to be reduced from a corrosion area to a stable area, thereby realizing the electrochemical protection of the metal. Wherein the TiO is2The photoelectric material has the characteristics of unique photoelectric property, good stability, no toxicity, low price and the like, and is widely researched by scientific researchers. In the research of photocathode protection technology, a photoelectrochemical cell is an indispensable device.
Generally, the photoelectrochemical cell has two structures of a single chamber and a double chamber, and referring to fig. 1, fig. 1 shows a single chamber photoelectrochemical cell, referring to fig. 2, fig. 2 shows a double chamber photoelectrochemical cell, TiO2When the coating is directly coated on the protected metal, a single-chamber photoelectrochemical cell is generally adopted. TiO 22When the coating is coated on conductive glass to prepare a photo-anode, a double-chamber photoelectrochemical cell is generally adopted. The protected metal and reference electrode are installed in the test chamber, and the photo-anode is installed in the photo-reaction chamber, and the solution media of the two chambers are different, so that the connection part is separated by a nafion membrane to prevent mutual pollution.
