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.
