Embodiment 1

[0036] The transparent conductive substrate adopts the FTO (F-doped tin oxide) conductive glass of Japan Nippon Sheet Glass Company. The conductive glass was cleaned in an ultrasonic water bath and then dried, and a Sn film of 100nm was evaporated.

[0037] Then an anodic oxidation process was performed to prepare SnO 2 Nanopore structure such as figure 1 . The conductive substrate 1 on which the Sn thin film has been evaporated is connected to the positive pole of a DC constant voltage power supply, and the platinum sheet is connected to the negative pole, and put into a corrosion solution for anodic oxidation. The corrosion solution is 0.5mol / L oxalic acid solution, the voltage between positive and negative electrodes is 8V, and the voltage application time is 8min. Ensure that the distance between the conductive substrate 1 of the Sn film and the platinum sheet is about 2 cm. Finish taking out the conductive substrate 1 of the Sn thin film, put into deionized water to c...
