초록
본 연구에서는 수열반응법을 이용하여 3차원 구조를 갖는 NiCo2O4 입자를 합성했다. 수열합성에서 반응조건[Ni]/[Co] 비율, 반응시간과 열처리온도를 달리하여 입자의 조성과 형상을 조절했다. 최적의 조건을 결정하고자 XRD, SEM을 통해 입자를 분석하였으며, [Ni]/[Co] 1:2 비율, 반응시간 12시간, 열처리 400°C 4시간 조건에서 3차원 구조를 갖는 단일상의 NiCo2O4가 합성하였다. 합성된 NiCo2O4 나노구조체의 글루코스 센서 특성평가 결과, 글루코스에 대해 높은 민감도와탁월한 선택성을 나타냈다. 본 연구를 통해 합성한 NiCo2O4 나노구조체는 향후 비효소 기반 전기화학적 글루코스 센서로널리 응용될 수 있을 것으로 기대된다.
Abstract
In this study, we prepared NiCo2O4 nanoparticles with large surface area by hydrothermal synthesis. In order to optimize the processing conditions for spinel NiCo2O4 nanoparticles with large surface area, experimental variables including concentration of Ni and Co precursor, reaction time, and temperature for post-heat treatment were evaluated. Optimized conditions for spinel NiCo2O4 with large surface area were [Ni]/[Co] 1:2 ratio, reaction time for 12 h, and post-heat treatment at 400°C. To investigate the feasibility as potential application for glucose sensor, electrochemical tests of the prepared NiCo2O4 nanoparticles in response to glucose was performed, which suggests that the NiCo2O4 can be suitable fora non-enzymatic-based electrochemical glucose sensor based on its high sensitivity and selectivity for glucose detection.
