Abstract

Carbon doping from a Ti precursor in TiO synthesized by a hydrothermal method was studied. The structural, optical and morphological study of the deposited material was carried out using X-ray diffraction, UV-vis spectroscopy and scanning electron microscopy characterization techniques. The elemental composition of the TiO deposited with different precursor concentrations was studied using X-ray photoelectron spectroscopy and electron dispersive X-ray spectroscopy. The amount of elemental carbon in the TiO matrix is found to be increased as the Ti precursor concentration is increased, which strengthens the proposed idea of carbon doping a Ti precursor.

摘要

研究了通过水热法合成的TiO中来自Ti前驱体的碳掺杂。使用X射线衍射、紫外可见光谱和扫描电子显微镜表征技术对沉积材料进行了结构、光学和形态学研究。使用X射线光电子能谱和电子色散X射线能谱研究了不同前驱体浓度下沉积的TiO的元素组成。发现随着Ti前驱体浓度的增加，TiO基体中的元素碳含量增加，这强化了碳掺杂Ti前驱体的观点。
