摘要

本研究主要目的為合成石墨烯(Graphene, GR)並且將其結合奈米碳管(Carbon nanotubes, CNTs)、酞菁、奈米金屬…等材料之性質探討，並且將上述材料應用於葡萄糖生物感測器、葡萄糖/氧氣生物燃料電池、聯胺與亞硝酸鹽感測器。本實驗並且利用一個簡單的電化學還原法制備氧化石墨烯奈米碳管複合材料並且結合葡萄糖氧化酵素共同修飾於玻璃碳電極上來制備出一個效果良好的葡萄糖感測器。此葡萄糖感測器並且可以應用於葡萄糖/氧氣生物燃料電池，可得到46 μW cm-2 的功率密度。氧化石墨烯結合鐵酞菁奈米材料可用來對聯安做即時偵測。利用簡單的電化學還原法可將氧化石墨烯結合鈷酞菁奈米材料製備一個有效率的葡萄糖感測器。氧化石墨烯結合鉍奈米金屬修飾於玻璃碳電極上可得到對聯胺偵測性良好的聯胺感測器。利用簡單的微波合成方法製備氧化石墨烯與乙烯亞胺/奈米金粒子，在高濃度為他命C溶液中選擇性偵測多巴胺。

This thesis study reports the synthesis and characterization of graphene (GR) based composite materials with carbon nanotubes (CNTs), phthalocyanines, metal nanoparticles and their applications as biosensors, biofuel cells and sensors. GR-CNTs hybrid was prepared by a simple solution approach to study the direct electrochemistry of glucose oxidase (GOx) and a gluose biosensor was demonstrated. Additionally, the hybrid was employed as anode for the construction of the membraneless glucose/O2 biofuel cell to harvest maximum power density up to 46 μW cm-2. A composite of GR and cobalt phthalocyanine (CoPc) was prepared by a simple chemical reduction to demonstrate a sensitive glucose biosensor. Furthermore, a glucose/O2 biofuel was assembled by exploring the GR-CoPc/GOx as anode. A simple chemical reduction method was described for the decoration of bismuth nanoparticles (Bi) at GR nanosheets and the resulting composite exhibited excellent electrocatalytic ability towards detection of hydrazine. GR/Polyethyleneimine (PEI)/gold nanoparticles (Au NPs) composite was prepared by a simple microwave assisted synthesis method and employed for the selective determination of dopamine in presence of high concentration of AA.
