Abstract

The fabrication of nanoceramices and nanomaterials with desirable morphology, structure, and particle size is one of the most important fields in the nanoscience. In order to achieve this goal, the sol–gel method is one of the most applicable methods which allow us to attain desirable structures by changing some parameters. This review focuses on the synthesis of some MTiO3 (M = transition metals) by different routs owing to the technological importance of this group of materials. It also investigates different properties of such materials including photocatalytic, dielectric, optical and electrocatalytic behaviors. The conventional titanates of MnTiO3, FeTiO3, and CoTiO3 are introduced and furthermore, their syntheses have been clarified by proposing a related mechanism. The effects of reactants concentration, time and temperature reaction, surfactant, M2+ and Ti4+ sources, etc. on the particle size, morphology, and some properties of the obtained nanomaterials have been investigated. The size and morphology of the as-synthesized samples are studied by the X-ray diffraction, scanning electron microscopy and transmission electron microscopy images. The optical, magnetic, and photocatalytic properties of the MTiO3 are studied as well.

摘要

具有期望的形态,结构和粒径的纳米陶瓷和纳米材料的制造是纳米科学中最重要的领域之一。为了实现这一目标,溶胶-凝胶法是最适用的方法之一,它使我们能够通过更改某些参数来获得所需的结构。由于这组材料的技术重要性,本文的重点是通过不同的路线合成某些MTiO 3(M =过渡金属)。它还研究了这种材料的不同特性,包括光催化,介电,光学和电催化行为。MnTiO 3,FeTiO 3和CoTiO 3的常规钛酸盐介绍了它们的作用,并通过提出相关的机理阐明了它们的合成。研究了反应物浓度,时间和温度反应,表面活性剂,M 2+和Ti 4+来源等对所得纳米材料的粒径,形态和某些性能的影响。通过X射线衍射,扫描电子显微镜和透射电子显微镜图像研究了所合成样品的尺寸和形态。还研究了MTiO 3的光学,磁性和光催化性能。
