Structural and Electrochemical Behaviors of ZnO Structure: Effect of Different Zinc Precursor Molarity

This research synthesised zinc oxide (ZnO) structure by a hydrothermal method. ZnO samples were prepared using different molarities of (Zn) precursor, ranging from 0.10 to 0.16 M. Structural and morphological properties characterised X-ray diffraction (XRD) scanning electron microscopy (SEM). The XRD patterns show that all are prominently grown along the three peaks at (001), (002) (101) planes. sample with M Zn precursor has highest peak orientation plane. average crystallite sizes for 0.10, 0.12, 0.14 48, 51, 49 31 nm, respectively. smallest size lowest tensile strain. SEM images randomly oriented diameters 209, 325, 295 348 nm when electrochemical behaviour was determined through cyclic voltammetry (CV) measurement. In CV curve, calculated specific capacitance value 3.87 Fg−1. 2.11 Therefore, changing molarity could change structural properties. provides optimal result.
