Embodiment 1
[0025] (1) Configure CuSO separately 4 (Concentration is 1mol / L), C 6 h 12 o 6 (concentration is 2mol / L) and NaOH (concentration is 2.5mol / L) solution 25 mL each; the CuSO 4 The solution was added into a 150 mL three-neck reaction flask, stirred at room temperature, and NaOH solution was slowly added, and the stirring was continued for 10 min after the addition, to obtain Cu(OH) 2 slurry, warm to 50°C, and bring the heat to 50°C 6 h 12 o 6 The solution was added to the reaction flask and reacted at constant temperature for 1 h to prepare Cu 2 The O slurry was suction filtered, washed three times with water, then washed three times with absolute ethanol, and dried at 60 °C for 24 h to obtain Cu 2 O;
[0026] (2) Weigh the Cu obtained in step (1) 2 Put 100 mg of O, 34 mg of cobalt chloride hexahydrate, and 3.333 g of SDS into a beaker, add 50 mL of distilled water and 50 mL of absolute ethanol, sonicate for 5 min, stir for 10 min, and then add 40 mL of 1.0 mol / L Na 2 S...
