| Summary: | 碩士 === 國立臺灣科技大學 === 化學工程系 === 104 === Heteroatom doping can endow carbon nanomaterials with various enhanced optical, structural, and physicochemical properties, making carbon nanomaterials become a promising material in various applications including nanoelectronics, catalysis, energy storage, functional composites, and biomedical applications. However, current synthesis methods usually involve complicated vacuum systems, making it difficult to enable industrial-scale production. Consequently, the development of a controllable synthesis of heteroatom-doped carbon nanomaterials at atmospheric pressure will lead to important advances on both scientific studies and innovation applications. Therefore, we demonstrate a wet-chemistry-assisted pretreatment substitution method to produce heteroatom-doped carbon nanomaterial with varying heteroatoms including boron (B), sulfur (S), nitrogen (N) and phosphorus (P), which is under atmospheric pressure.
The thesis is organized in follows. Chapter 1 gives an introduction to the heteroatom-doped carbon nanomaterials. It provides a brief historical overview of synthesis, properties, and related applications of heteroatom-doped carbon nanomaterials. Chapter 2 describes the experimental set up and several characterization methods has been used. Chapter 3 discusses the properties of multi-walled carbon nanotubes (MWNTs) doped with sulfur atoms, including the increasing of conductivity and dispersion. Chapter 4 shows the extension of our proposed method, it is widely used on different kind of precursors doped on also graphene and related materials. Furthermore, the as-prepared sulfur-doped MWNTs shows the potential for surface enhanced Raman spectroscopy (SERS) substrate, which is discussed in chapter 5.
