We demonstrate the results of a single-step in-situ synthesis that produces surface decoration of partially agglomerated amorphous silica nanospheres (diameter ∼45 nm) with SnOx nanocrystals of diameter 3−6 nm. The technique would appear to be useful for the dispersal of extremely small tin oxide nanostructures on a silica nanosurface to produce improved sensors and catalysts. Preliminary results indicating improved kinetic activity on this nanoscale are reported.
