摘要/Abstract

摘要：

溶液法是一种反应温和、易控制且常用的合成方法。目前已报道的溶液法制备TiSe₂时通常采用三辛基膦(TOP)为溶剂, 但这种试剂有毒, 对人体和环境都有潜在的危害。本研究通过简单的、无TOP的溶液法成功地制备了单分散的六边形TiSe₂纳米片, 并通过调整反应时间研究TiSe₂纳米片的形貌演变规律。利用XRD、SEM、EDS和紫外-可见漫反射对其物相、形貌、元素以及光学性能进行了系统的表征; 根据SEM结果对其生长过程及形貌演变规律进行了研究, 并提出一种螺旋状逐层生长的机理; 分析考察了TiSe₂纳米片对罗丹明B(RhB)的光催化活性, 发现其具有高于P25的降解能力, 这表明TiSe₂纳米片作为光催化材料具有广阔的应用前景。

Abstract:

Solution method is a mild, controllable and commonly used synthetic method. However, the reported solution methods for the preparation of TiSe₂ nanosheets usually use trioctylphosphine (TOP) as solvent. TOP is poisonous and potentially harmful to the human body as well as the environment. In this paper, hexagonal TiSe₂ nanosheets were synthesized by simple solution method without TOP. The shape evolution of TiSe₂ nanosheets was investigated by adjusting the reaction time. The crystal phase, morphology, elements, and the optical property of TiSe₂ nanosheets were characterized by X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), and UV-Vis spectroscopy, respectively. The spiral growth steps can be clearly observed in SEM images. A spiral layer by layer growth mechanism was proposed based on the morphology evolution of TiSe₂ nanosheets. The photocatalytic activity of TiSe₂ nanosheets was evaluated by the degradation of RhB under sun light irradiation. Compared with the commercial P25, the as-prepared TiSe₂ nanosheets exhibit a superior photocatalytic activity, which indicates that TiSe₂ nanosheets are promising candidate as photocatalytic material for environmental protection.
