Selectivity in nanoreactors : A hybrid yolk–shell nanostructure that contains gold nanoparticles in the core and thermosensitive microgel poly( N ‐isopropylacrylamide) (PNIPA) as shell is presented. The catalytic selectivity of Au‐PNIPA nanoparticles for the reduction of hydrophilic 4‐nitrophenol and more hydrophobic nitrobenzene with NaBH 4 can be tuned through the volume transition of PNIPA shell (see picture).
