[0035] Example 1
[0036] (1) Preparation: Cut the purchased copper sheet into 1cm×1cm size copper sheet, immerse the cut copper sheet in 2M dilute hydrochloric acid, ultrasonically clean it in an ultrasonic cleaner for 10 minutes, and perform deoxidation treatment. Rinse with deionized water for 2 to 5 times for later use; wash the beaker with tap water and distilled water in turn, dry and set aside;
[0037] (2) Reaction step: combine a certain amount of elemental Se powder and Na 2 Add a small amount of deionized water to S, and heat it in a blast drying oven at 80℃ until the selenium powder is completely dissolved, the solution becomes wine red, and an aqueous solution with sodium sulfide concentration of 0.0100g / ml and elemental Se concentration of 0.0002g / ml is obtained. Seal the beaker with sealing glue and place it in a device with constant temperature function, such as a biochemical incubator, at a constant temperature of 15°C, put the deoxidized copper sheet into the reac...
