Dear academic predecessors, as a newcomer, there may be a naive question, which is why the method of reducing metals using NaBH4 reported in other papers cannot be reduced to the metal size reported in it, and my reduction is always too large. Therefore, do you have any better methods for reducing to very small metal nanoparticles(1.5nm-3nm), especially Pd, or any suggestions?
using hydrongen peroxide solution reduces the particle size, ucan use long time stirring with slower rate. u can use sonication to reduce AGGREGATION OR AGGLOMERATION
Each system requires synthesis optimization. Everything depends on the following application, for instance such unstable particles is easier to immobilize on the porous substrate if the future application is catalysis.Article Cryogels with Noble Metal Nanoparticles as Catalyst for “Gre...
