Title: Nanoporous Pt(Au) Alloys for the Enhanced, Non–enzymatic Detection of Hydrogen Peroxide under Biofouling Conditions

Journal Article · · Electroanalysis

The non-enzymatic electrochemical sensing of hydrogen peroxide (H2O2) is described. This study utilized a 3D bicontinuous nanoporous platinum-gold alloy-based sensor (NP-Pt(Au) electrode), which has a morphology that resembles a molecular sieve. SEM and CV were used to evaluate the morphological and electrochemical characteristics of the NP-Pt(Au) electrodes. The cathodic voltammetric response of H2O2 was enhanced at the NP-Pt(Au) as compared to planar Pt electrodes. Further, the nanoporous electrode was able to maintain the H2O2 voltammetric profile even in the presence of the biofouling agent, serum albumin. Its application as a non-enzymatic sensor for the amperometric measurement of H2O2 was explored.
