Abstract
Nanoporous (NP) PtAu alloy is easily fabricated by a simple and general dealloying method. Characterized by three-dimensional nanospongy architecture with a typical dimension around 5Â nm, the as-prepared NP-PtAu alloy shows superior sensing performance towards glucose and hydrogen peroxide (H2O2) with highly sensitive response compared with commercial Pt/C and NP-Pt catalysts. Importantly, NP-PtAu exhibits excellent amperometric durability and long-term stability for H2O2 and glucose. After coating additional nafion on the working electrode, NP-PtAu shows a good anti-interference towards ascorbic acid, uric acid, and dopamine during glucose detection. NP-PtAu alloy holds great application potential for electrochemical sensing with simple preparation, high catalytic activity, and high structure stability.
