Spatially controlled reactions at the nanoscale have attracted increasing interest for fundamental chemistry and for the engineering of novel functional materials. Herein, we demonstrate that pH-triggered reduction of silver ions preferentially occurs at the inner walls of porous and citrate-capped...
