Abstract
A nanoporous gold film (NPGF) was prepared onto a gold electrode surface using a facile and green electrochemical approach via anodization at 2.0 V in 0.5 mol L-1 H2SO4. The as-synthesized NPGF electrode showed superior electrocatalytic activity towards dissolved oxygen reduction at a low overpotential (-0.045 V) along with 2-fold enhanced sensitivity. (AU)
