摘要：
Carbon nanotubes (CNTs)-modified titania nanotube (NT) arrays are prepared by vapor-growing CNTs in the inner of titania NTs. Pt nanoparticles of similar to 3 nm in diameter are uniformly decorated on the as synthesized titania-supported CNTs (TiO2/CNTs) electrode, showing remarkably improved catalytic activities for the oxidation of hydrogen peroxide. The consequent glucose biosensor fabricated by modifying TiO2/CNT/Pt electrode with glucose oxidase (GOx) presents a high sensitivity of 0.24 mu A mM(-1) cm(-2) to glucose in the range of 0.006 mM to 1.5 mM with a response time of less than 3s and a detection limit of 5.7 mu M at 3 signal/noise ratio.
