I am working on grafting two nanoparticles of various sizes, i.e., one is 10-20nm, while the other is around 100nm. Can anyone please tell me a simple, robust, and efficient grafting technique to decorate smaller nanoparticles on top of the larger nanoparticle?
Can you please provide more information about these nanoparticles?
the different size of nanocatalyst dependes on the type and natural of reaction
ex.the low amount of Pt doped on TiO2 will more active that the same amount of Au doped on TiO2 with different sizes to produce hydrogen and formaldehyde from alcohol.
Disperse larger particles in high boiling coordinating liq sonicate or heat for a while cool and then add smaller particles stir only and then workup via centrifugation process.
May be it will work
Alternatively
Insitu try synthesis of large particles as core and then small particles as shell and vice versa
Paolo Passaretti TO explain it more, I want to graft small nanoparticles of TiO2 over large BaTiO3 Nanoparticle, however, not with conventional techniques but a simple, robust, and efficient grafting technique. Regards.
Respected Pawan Kumar Khanna, Thanks for your kind answer. The technique you specified is more like a weak physical bonding of two nanoparticles. I want to chemically graft small nanoparticles on big nanoparticles. Respected, sir if you have any suggestion, please guide. Regards.
