Preparation of Nano Au and Pt Alloy Microspheres Decorated with Reduced Graphene Oxide for Nonenzymatic Hydrogen Peroxide Sensing.
Langmuir : the ACS Journal of Surfaces and Colloids 2018 Februrary 14
The flourish of nanotechnology has brought new vitality to the research and development of electrochemical sensing materials. In this work, we successfully synthesized Nano Au and Pt alloy microspheres decorated with reduced graphene oxide (RGO/nAPAMSs) by a simple, facile, and eco-friendly one-step reduction strategy for the fabrication of highly sensitive nonenzymatic H2 O2 sensing interfaces. Energy-dispersive X-ray spectroscopy mapping (EDX mapping), energy-dispersive X-ray spectroscopy analysis (EDX), transmission electron microscopy (TEM), Fourier transform infrared spectrum (FT-IR), and X-ray diffraction spectrum (XRD) were employed to characterize RGO/nAPAMSs from a microscopic perspective. The results of cyclic voltammetry and chronoamperometry exhibited excellent electrochemical behaviors toward H2 O2 , with a rapid response time within 5 s, remarkable sensitivity of 1117.0 μA mM-1 cm-2 , wide linear range of 0.005 to 4.0 mM and lower detection limit of 0.008 μM (S/N = 3), which provide RGO/nAPAMS not only a promising prospect for the quantitative detection of H2 O2 but also a potential application in other fields of sensors. Moreover, further analysis showed the principles of the superior H2 O2 sensing performance of RGO/nAPAMSs. This discovery provides a significant contribution to future study in nonenzymatic H2 O2 sensing based on Nano Pt, Nano Au noble metal electrocatalysts.
