Embodiment 1
[0027] a. Bi 2 WO 6 Preparation: Weigh 0.3g of bismuth nitrate pentahydrate and dissolve it in 20mL of dilute nitric acid with pH=1, stir magnetically until it dissolves, and count it as solution A; weigh 0.17g of sodium tungstate dihydrate and dissolve it in 20mL of deionized water, Stir magnetically until dissolved, and count as solution B; add solution B dropwise to solution A, stir for 20 minutes, transfer into a 50 mL autoclave, and heat at 180 ° C for 12 hours; after natural cooling to room temperature, anhydrous ethanol and distilled water are alternated Wash and dry overnight at 60°C in a vacuum oven;
[0028] b. Preparation of Bi 2 WO 6 / ITO electrode: Weigh the pre-prepared Bi2 WO 6 The powder was added to deionized water and sonicated to obtain a suspension with a concentration of 1 mg / mL; 30 μL of Bi was dripped on the surface of the pre-cleaned ITO electrode. 2 WO 6 The suspension was dried at 40°C for 2 hours for use;
[0029] c. Biometric recognition and ...
Embodiment 2
[0032] a. Bi 2 WO 6 Preparation: Weigh 0.3g of bismuth nitrate pentahydrate and dissolve it in 20mL of dilute nitric acid with pH=1, stir magnetically until dissolved, and count as solution A; weigh 1.49g of ammonium tungstate and dissolve it in 20mL of deionized water, stir magnetically Until dissolved, it was counted as solution B; solution B was added dropwise to solution A, stirred for 20 minutes, transferred to a 50 mL autoclave, heated at 160 ° C for 16 hours; after naturally cooled to room temperature, washed alternately with absolute ethanol and distilled water and Dry overnight at 40°C in a vacuum oven;
[0033] b. Preparation of Bi 2 WO 6 / ITO electrode: Weigh the pre-prepared Bi 2 WO 6 The powder was added to deionized water and sonicated to obtain a suspension with a concentration of 1 mg / mL; 30 μL of Bi was dripped on the surface of the pre-cleaned ITO electrode. 2 WO 6 The suspension was dried at 40°C for 2 hours for use;
