چکیده
This paper presents significant findings regarding the impact of ZnO and graphene oxide (GO) doping on the structural and electrical properties of potassium ferrate nanostructures. The samples were synthesized using a thermal treatment method at temperatures of 773, 873, and 973 K. The structural characteristics, optical and magnetic properties of the synthesized samples were analyzed using various techniques. The photocatalytic activity of K2FeO4/ZnO nanoparticles under visible light irradiation was investigated using methylene blue (MB) degradation as a probe reaction. The results indicated a significant enhancement in photocatalytic activity when GO was incorporated into the K2FeO4/ZnO nanocomposite. The dielectric constant and dielectric loss were measured at room temperature across a frequency range of 4 to 8 MHz using an LCR meter. Our findings reveal that the addition of graphene oxide (GO) did not result in a significant enhancement in dielectric permittivity compared to potassium ferrate/ZnO nanocomposites. Therefore, potassium ferrate-based nanocomposites, given their favorable dielectric properties, are promising candidates for a wide range of applications, including devices operating at microwave frequencies, various optical and microelectronic applications, and as materials for microwave absorption.
