초록
본 연구에서는 금 나노입자로 전착된 전극위에 3-MPA로 개질된 자가조립 단층 전극의 순환전위법의 특성을 조사하였다. 또한 전극 주변에서 전자와 이온의 이동현상을 해석하였다. 반무한확산모델을 채택하여, 물질전달 지배계에 대하여 지배방정식과 경계조건을 유도하였다. 자가조립단층 전극에 대한 순환전위법의 수치해를 구하기 위하여, 양함수 유한차분법을 적용하여MATLAB 프로그램을 작성하여 해를 구현하였다. 자가조립으로 개질된 전극에 대한 본 CV 용프로그램은 3-MPA으로 개질된 금 나노입자 SAM 전극의 순환전위법 실험결과를 잘 설명하고있음을 확인할 수 있었다.
Abstract
In this paper, we have investigated the characteristics of cyclic voltammetry of a self-assembled mono-layer(SAM) electrode which was modified by 3-Mercaptopropionic acid(3-MPA) on gold nanoparticle(AuNP)-deposited electrode. Also, the transport phenomena of electrons and ions around the electrode have been analyzed. The governing equation and its boundary conditions by adopting the semi-infinite diffusion model were formulated for the mass-transfer dominant system. In order to obtain the numerical solutions of cyclic voltammetry(CV) on SAM electrodes, MATLAB program was implemented by applying the explicit finite difference method. Resulting CV program for the SAM-modified electrode was verified in good agreements with the experimental CV results for the 3-MPA on AuNP electrode.
