摘要：
Pt nanoparticles (PtNPs)/polypyrole (PPy) composites were successfully prepared through a facile one-pot interfacial polymerization of pyrrole by using H2PtCl6 as the oxidant for the first time. The as-prepared PPy was granular particles with particle size within a few hundred nanometers, on which PtNPs (1.7-3.5) nm were homogeneously dispersed. The PtNPs/PPy composites displayed excellent electrocatalytic activity toward redox of H2O2. The non-enzyme sensor constructed with PtNPs/PPy composites displayed good sensing ability toward H2O2 at -0.1V with a significantly high sensitivity of 6056AmM(-1)cm(-2) and a low detection limit of 1.8M (S/N=3).
