Popis:	This work is an extension on a previous study on the effect of electrode size on catalyst performance. Through these two sets of work, it is shown that there exists a critical electrode size for maximum catalytic activity. Gold nanoelectrode arrays produced by template synthesis and electroless deposition were utilized for all the experimental studies. The comparison of electrocatalytic activity was performed in 0.1 M KOH for the hydrogen evolution reaction. A proposed theory explaining the reasons for the observed change in catalytic performance is introduced in this work. Keywords: Size effect, Catalyst, Template synthesis, Electrochemical impedance spectroscopy, Capacitance
