Nano composite bimetallic or core shell formed by multi step chemical reduction method . To test the activity, nano composites must be dissolved in a suitable solvent. But is there any procedure to dissolve formed nano composite with out any carbon support or any support .
Hi Sunil Kumar,
Bimetalic nano-particles structure depend on the metal pair. I'm not sure I understand your question. ]f you want to use this composite as a catalyst or absorbent , its solubility would be a disadvantage. But if you still want it to be dissolved in a solvent, you could cover the shell with a polar coating such as silica compounds or an appropriate surfactant.
Based on our results we are not able to tell anything about the solubility. There is probably some rearrangement of the metals of bimetallic nanoparticles, but this effect has been thoroughly studied in previous researches. See for example, M. Lukaszewski, A. Czerwinski, Electrochim. Acta 48, 2435 (2003); J.S. Jirkovsky, I. Panas, S. Romani, E. Ahlberg, D.J. Schiffrin, J. Phys. Chem. Lett. 3, 315 (2012). In both papers it is demonstrated that by changing the electrochemical conditions the surface of the material can be enriched with Pd or Au.
