Abstract

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 R_Ct and C_dl 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.

表面合成具有增强光催化降解和传感器应用的偏氰酸锌纳米复合材料

本文采用水热法制备了钒酸锌纳米复合材料（ZVNC-Zn3V2O8）。利用扫描电镜（SEM）、紫外可见光谱（UV-visible spectroscopy）、PXRD和透射电镜（TEM）等分析了纳米复合材料的形貌、晶体结构、粒径和光学性能。合成的纳米复合材料的平均晶粒尺寸约为24.48 nm。测量到的能隙为3.4 eV，使材料适合在紫外线（UV）光照射下进行降解研究。其中，对孔雀石蓝和孔雀石绿的降解效率分别为87.15%和92.64%。此外，同样的化合物被用于检测抗坏血酸，充放电研究显示，RCt和Cdl值极低，分别为82.4 C和0.000125 F。这些结果表明，ZVNC中的电荷传递过程是高效的，可以实现快速有效的能量传输。这些特性表明ZVNC在能源和环境领域的应用具有巨大的潜力，为其材料特性提供了有价值的见解。图形抽象
