The NPG thin film with a roughness factor of about 25 was fabricated by electrochemically dealloying Si out of a relevant AuSi alloy co-deposited on Si substrate. The oxidation behavior of phenol on the as-synthesized NPG thin film was then observed using cyclic voltammetry and amperometry techniques. It was found that the NPG electrode exhibited large linear detection range (2-300 M), good sensitivity (96 nA/M) and relatively low detection limit (2 M). The results of this study reveal a high potential for development of sensors based on NPG platform for the determination of pollutants in practical, diverse environmental conditions.
