碳材料具有多種不同結構且具備廣泛的應用性，例如鋰電池及燃料電池中的電極、印表機的碳粉、補強輪胎的碳煙等等。近年來隨著奈米科技的發展發現了奈米碳管及奈米碳球，且其特性與利用性引起許多人的研究興趣。在本研究中，我們試圖進一步瞭解碳物種結構與化學性質的對應關係。我們選擇石墨為理想模型作為研究對象，以程溫脫附法(TPD)為主要研究方法，並輔以TEM及XRD等儀器確認從TPD所得到的結果。
我們選擇了四類探測分子，分別為苯環類分子、環己烷類分子、長鍊分子與醇類分子，試圖瞭解不同類分子與石墨間的交互作用。具有分支的苯環類分子在石墨上有強的吸附作用，長鍊分子的吸附力其次，醇類分子和1,3-hexadiene在石墨上有兩個以上的吸附位置，其吸附行為較複雜。隨著分子種類的不同，其脫附活化能與石墨覆蓋量的關係也稍有差異，不過變化幅度不會太大。同一種類的探測分子其變化趨勢則相近。我們認為除了石墨表面，分子也會藉由擴散作用進入石墨的層間結構中進行吸附，且能在此產生愈大立體阻礙的分子其吸附量也愈大。石墨的孔徑改變或增加石墨上的官能基可能會對吸附分子的脫附活化能產生影響，且其影響大於石墨覆蓋量的變化。

The carbonaceous material possesses many kinds of structures and extensive applicability. For example, they are used for lithium battery and fuel cell electrode, printer’s carbon powder, and for the reinforcement of tire. The carbon nanotube and carbon nanocapsule are the novel carbonaceous materials. Their unique property and applicability have attracted a lot of investigation. In this research, we attempt to understand the relationship between the structures and chemical properties of the carbonaceous material. Graphite is an ideal model for this study, and the temperature-programmed desorption method is applied in this investigation. XRD and TEM are also used to support the results of TPD method.
Four kinds of exploration molecules are chosen. They are benzene-like molecules, cyclohexane-like molecules, long chain molecules and alcohol-like molecules, respectively. We attempt to find out the differences of the interaction between graphite and various kinds of molecules. The benzene-like molecules with alkyl branch are strongly adsorbed on graphite. The adsorption of long chain molecules on graphite is the next. There are more than one kind of adsorption site on graphite available for 1,3-hexadiene and alcohol-like molecules adsorption. The adsorption behavior of 1,3-hexadiene and alcohol molecules are more complicated. Although the desorption activation energy for different molecules on graphite with different coverages are different. The difference in the desorption activation energy are negligible. The tendency of change is similar for the same kind of molecules. The adsorbed molecules can also diffuse into graphite’s interlayer structure. The interlayer distance of graphite can be changed by the diffusion process of the adsorbed molecules. The desorption activation energies may change when graphite’s pore size changes or functional groups exist on graphite surface. The changes of the activation energy caused by the change of graphite’s pore size or by the surface functional groups are more prominent than the changes induced by the coverage difference of adsorbed molecules on graphite.
