Embodiment 1
[0098] Synthesis of Cu-Sn Particles
[0099] will contain 12 mmol of CuCl 2 and 10mmol of SnCl 2 The mixed aqueous solution was slowly added dropwise to the NaBH containing 60mmol 4 , the resulting solution was stirred for 1 hour to induce a reaction between them, and the formed particles were purified by centrifugation to obtain Cu 6 sn 5 bimetallic nanoparticles.
Embodiment 2
[0101] Synthesis of Cu-Sn Particles
[0102] will contain 10 mmol of CuCl 2 and 10mmol of SnCl 2 The mixed aqueous solution was slowly added dropwise to the NaBH containing 100mmol 4 In an aqueous solution of , the resulting solution was stirred for 10 hours to induce a reaction between them, and the formed particles were purified by centrifugation to obtain Cu 6 sn 5 bimetallic nanoparticles.
Embodiment 3
[0104] Synthesis of Cu-Sn Particles
[0105] will contain 12 mmol of CuCl 2 , 10mmol of SnCl 2 And 50mmol of trisodium citrate mixed aqueous solution was added dropwise to the NaBH containing 60mmol within 1 hour 4 in an aqueous solution, the resulting solution was stirred for 24 hours to induce a reaction between them, and the formed particles were purified by centrifugation to obtain Cu 6 sn 5 bimetallic nanoparticles. exist figure 2 with image 3 are shown in Cu 6 sn 5 SEM images and XRD patterns of bimetallic nanoparticles.
