Synthesis of ZnO, SnO2, (ZnSnO3) perovskite structure by chemical method and evaluation of antimicrobial activity

This study utilises a basic and efficient chemical method to produce perovskite zinc stannate (ZnSnO₃), nano-zinc oxide (ZnO), and nano-tin oxide (SnO₂) for the purpose of manufacturing. With the aid of sophisticated analytical techniques, an exhaustive investigation of physical and chemical characteristics of the manufactured materials was carried out. The following techniques were used in this work: XRD, FE-SEM, and UV–Vis. From the results obtained in this work, it can be mentioned that the synthesis was done in an appropriate form since the compounds prepared have dimensions at the nanoscale and a homogeneous crystalline structure. With an overview of these nanostructure materials in acting as antibacterial agents, the screening of many pathogenic microorganisms, including Gram-positive and Gram-negative bacteria along with a fungal strain, was considered. The superior antibacterial efficacy of ZnSnO3, among all the materials under investigation, is due to the peculiar perovskite structure of the material, which can effectively interact with microbial cells, bringing about a significant suppression in their growth. On the contrary, SnO₂ showed no detectable antibacterial effect. The above situation indicates that composition and structure has a great impact on the biological performance of its constituents. Results shed light on the effectiveness of ZnSnO₃ as an antibacterial agent and hence can be extended to various medical and agricultural applications. Due to the presence of this antimicrobial agent, it has become very effective and possible to fight microbial diseases in an environmental-friendly way and in an economic manner. These results reveal, in a way, the role that the perovskite structure plays in improving the biological activity and, consequently, open a path for using these kinds of materials in the elaboration of environmentally benign antibacterial therapies.
