Example Embodiment
[0048] Example 1 Preparation of photoelectrochemical sensor
[0049] (1) Preparation of tungsten trioxide material
[0050] Dissolve 1.0 g of tungsten chloride in 35 mL of absolute ethanol. After stirring for 1 h at room temperature, transfer the mixed solution to an autoclave and react at 120 °C for 4 h. After the reaction, cool to room temperature naturally. The product was washed 3 times with absolute ethanol and ultrapure water each. After the washing, the product was dried at 40 °C for 10 hours to obtain sea urchin-like tungsten trioxide material;
[0051] (2) Preparation of bismuth sulfide nanorod materials
[0052] Dissolve 1.5 g of bismuth nitrate pentahydrate in 20 mL of ethylene glycol and stir at room temperature for 20 min. This solution is used as solution A; dissolve 1.2 g of sodium sulfide nonahydrate in 20 mL of ultrapure water and stir at room temperature for 10 min, this solution is used as solution B; dissolve 1.8 g of urea in 10 mL of ultrapure water, and stir eve...

[0098] Example 3 Construction of photoelectrochemical immunosensor
[0099] (1) Preparation of tungsten trioxide material
[0100] Dissolve 2.0 g of tungsten chloride in 50 mL of absolute ethanol. After stirring for 2 h at room temperature, the mixed solution was transferred to an autoclave and reacted at 180 °C for 8 h. After the reaction, it was naturally cooled to room temperature. The product was washed 3 times with absolute ethanol and ultrapure water. After washing, the product was dried at 60 °C for 12 hours to obtain sea urchin-like tungsten trioxide material;
[0101] (2) Preparation of bismuth sulfide nanorod materials
[0102] Dissolve 2.0 g bismuth nitrate pentahydrate in 30 mL ethylene glycol and stir at room temperature for 30 min. This solution is used as solution A; dissolve 1.5 g sodium sulfide nonahydrate in 50 mL ultrapure water and stir at room temperature for 20 min, this solution is used as solution B; dissolve 2.0 g of urea in 40 mL of ultrapure water, and stir...
