| 中文摘要 | polyaniline nanofibers (paninfs) have been facilely prepared by electrochemical polymerization of aniline monomers in acidic aqueous media without using any templates and surfactants. the subsequent treatment of such nanofibers with a agno3 aqueous solution leads to in situ chemical reduction of ag+ on them to form ag nanoparticles decorated paninfs (agnps/paninfs) nanocomposites. we investigated the catalytic activity and electrochemical properties of these nanocomposites. it is found that such nanocomposites exhibit excellent catalytic activity toward reduction of 4-nitrophenol to 4-aminophenol by nabh4 and exhibit remarkable catalytic performance for h2o2 reduction. the enzymeless h2o2 sensor constructed using the nanocomposites shows a fast amperometric response time of less than 3 s. the linear range and detection limit are estimated to be from 0.1 mm to 60 mm (r = 0.998) and 1.7 mu m at a signal-to-noise ratio of 3, respectively. we have fabricated a glucose biosensor by immobilizing glucose oxidase into the agnps/paninfs-modified glassy carbon electrode for glucose detection. this sensor exhibits good response to glucose. the linear response range is estimated to be from 1 mm to 12 mm (r = 0.997) at -0.58 v. the detection limit is estimated to be 0.25 mm at a signal-to-noise ratio of 3. |
