Description
Summary:碩士 === 國立臺南大學 === 自然科學教育學系碩士班 === 92 === ABSTRACT In this paper, the studies on electrocatalytic behavior of methanol and benzyl alcohol at Ni(tmdbta)n film modified electrode which are electropolymerization of macrocyclic nickel complex on glassy carbon working electrode by cyclic voltammetry. In alkaline buffer solution of pH=13, increase methanol or benzyl alcohol of different density, place into the modified electrode to carry on cyclic voltammetry scan, observe the current and potential of oxidizing peak. The reaction current that the methanol density causes will influence the oxidize current of NiⅡ. To change the scan rate and to study the influence of the current. In methanol or benzyl alcohol solution, analysis the electrode surface adsorbs by rotating disk electrode. The experiments show that difference structure between methanol and benzyl alcohol influence the ability of adsorb. Under different pH value of alkaline buffer solution, analyze the best operation scope of the reaction by calculating oxidation capacity. The scope is between pH=13.0~13.5, and further inquire the influence of [OH-] on the modified film.
