摘要

In this study, zinc vanadate nanocomposite (ZVNC-Zn3V2O8) was prepared by hydrothermal method. SEM, UV–visible spectroscopy, PXRD, and TEM were utilized to analyze the morphology, crystal structure, particle size, and optical properties of the nanocomposite. The average crystallite size of synthesized nanocomposite was deducted ~ 24.48 nm. The measured energy bandgap was 3.4 eV, making the material suitable for degradation studies under ultraviolet (UV) light exposure. Notably, the degradation efficiency for malachite blue and malachite green was 87.15% and 92.64%, respectively. Additionally, the same compound was utilized for the detection of ascorbic acid, and charge–discharge studies revealed extremely low RCt and Cdl values of 82.4 C and 0.000125 F, respectively. These findings indicate that the charge transfer process in ZVNC is highly efficient, enabling rapid and effective energy transmission. These properties suggest that ZVNC hold significant potential for applications in energy and environmental fields, offering valuable insights into their material characteristics.
