I want to make trimetallic nanoparticles of Mn-Ni-Si using chemical reduction method. I am using precursors as chlorides, for Mn and Ni it is easy to hydrate the chlorides but for SiCl4, if it is hydrated, it immediately forms SiO2 lumps in the solution. Can you suggest an alternative method for this and also the reducing agent which could be used for chemical synthesis of MnNiSi nanoparticles.
Hi Shakeel,
Thank you for the answer. For Ni/Au/Co synthesis, they use aqueous salts of metals as starting materials, but in case of Silicon, SiCl4 salt cannot be made aqueous because it is sensitive to moisture, it forms SiO2 which cannot be reduced by NaBH4 reduction.
Could you please suggest any other precursor/chemical method/ which will allow me to get trimetallic nanoparticle with Si as one of the element.
Thanks
Can you not use an anhydrous non aqueous solvent like DMF or THF? Admittedly, this may require alternative reducing agents -eg to generate a THF-BH3 complex from the NaBH4. But as you have discovered, you cannot use SiCl4 with any aqueous solution. One other question: do the anhydrous manganese and nickel chlorides dissolve in SiCl4?
