RESUMO
A low density CNT forest was fabricated by plasma enhanced chemical vapor deposition, and Ni nanoclusters were well distributed on the sidewall and on top of CNT forest by magnetron sputtering. The Ni deposition time plays an important role in electrochemical properties of the CNT/Ni electrodes, and the optimized deposition time is 150 to 240 s. Cyclic voltammetry and chronoamperometry were used to evaluate the catalytic activities of the CNT/Ni electrodes. The sensitivity of the glucose sensor based on a Ni24OS electrode is able to reach 1433 µA mM(-1) cm(-2), which is much higher than that found using a NiOS electrode.
