Embodiment 1
[0034] Preparation of Bi-In@Cu foam nanomaterials:
[0035] (1) Weigh 0.5mmol (0.1931g) of Bi(C 2 h 3 o 2 ) 3 Solid and 0.5mmol (0.1861g) of disodium edetate solid were added to a 100mL beaker, a certain amount of double distilled water was added and stirred at room temperature to dissolve until the solution was clear, then transferred to a 250mL volumetric flask, Recorded as solution A;
[0036] (2) Weigh 0.005mmol (0.0015g) of In(NO 3 ) 3 Add the solid to a 100mL beaker, add a certain amount of double-distilled water and stir at room temperature to dissolve until the solution is clear, then transfer to a 250mL volumetric flask, and record it as solution B;
[0037] (3) Take a 50mL beaker, add 15mL of solution A and 15mL of solution B respectively, and stir evenly at room temperature to obtain mixed solution C;
[0038] (4) Take a piece of 1.0cm×1.5cm×1.0mm copper foam, ultrasonically in 0.5M HCl and double-distilled water for 10 minutes, and then use absorbent paper t...
