| 中文摘要 | in this paper, we have reported a very simple strategy (combined sonication with sol-gel techniques) for synthesizing well-defined silica-coated carbon nanotube (cnt) coaxial nanocable without prior cnt functionalization. after functionalization with nh2 group, the cnt/silica coaxial nanocable has been employed as a three-dimensional support for loading ultra-high-density metal or hybrid nanoparticles (nps) such as gold nps, au/pt hybrid nps, pt hollow nps, and au/ag core/shell nps. most importantly, it is found that the ultra-high-density au/pt nps supported on coaxial nanocables (uascn) could be used as enhanced materials for constructing electrochemical devices with high performance. four model probe molecules (o-2, ch3oh, h2o2, and nh2nh2) have been investigated on uascn-modified glassy carbon electrode (gce). it was observed that the present uascn exhibited high electrocatalytic activity toward diverse molecules and was a promising electrocatalyst for constructing electrochemical devices with high performance. for instance, the detection limit for h2o2 with a signal-to-noise ratio of 3 was found to be 0.3 mu m, which was lower than certain enzyme-based biosensors. |
