Kalsiyum karbonat destekli çinko oksit malzeme üretimi ve karakterizasyonu

Calcium carbonate (CaCO3) is a type of chemical compound popularly known as limestone. CaCO3 is abundant in nature, and it has three types of crystal forms, namely aragonite, vaterite and calcite. On the contrary, the crystal form of zinc oxide (ZnO), zincite mineral is rare in nature. ZnO has many uses in fields such as the rubber industry, concrete manufacturing, and medical applications. In addition to all areas of use, its photocatalytic properties and being cheaper than TiO2, which is an efficient photocatalyst, allowed its use as a catalyst to be investigated. The most important principle of photocatalytic formation is the voids in the crystal structure. These voids will be more abundant in a defective crystal than in a perfect crystal. These gaps can be filled with additives used during crystallization. An excess amount of this substance, also known as an impurity, gives rise to composite materials with new properties such as ZnO/SnO2, NiO/TiO2, ZnO/In2O3, p-ZnO/TiO2. In this study, the CaCO3-ZnO composite was synthesized by a hydrothermal process. The size and morphological characteristics of the synthesized composite were characterized by SEM, XRD and BET analyses.
