From: Simple size-controlled synthesis of Au nanoparticles and their size-dependent catalytic activity

Dependence of the reaction rate of 4-nitrophenol reduction to 4-aminophenol by sodium borohydride catalysed by various sized Au NPs on their total surface at constant amount of gold in the reaction mixture (10 μmol/L). Experimental data are evaluated by linear (full line) and by quadratic function (dashed line).
