摘要

ZnO and Zn2SnO4 have attracted significant interest as multifunctional materials for photocatalysis and energy storage applications due to their superior physicochemical properties. In this study, ZnO/Zn2SnO4 (ZOS/T) nanostructures were synthesized using a ball milling process and subsequently annealed at different temperatures (250 °C, 300 °C, and 500 °C) to optimize their photocatalytic properties. The structural, morphological, elemental, and optical properties of the synthesized materials were characterized using X-ray diffraction (XRD), scanning electron microscopy (SEM), energy-dispersive spectroscopy (EDS), and UV-Vis spectroscopy. The photocatalytic efficiency of ZOS/T nanostructures was evaluated through the degradation of methylene blue (MB) under UV and visible light. The results demonstrated that increasing the annealing temperature enhanced crystallinity, reduced structural defects, and improved charge carrier separation, leading to superior photocatalytic activity. The sample annealed at 500 °C exhibited the highest degradation efficiency of 89% within 100 min, attributed to better charge mobility and lower recombination rates. These findings highlight the potential of ZnO/Zn2SnO4 composites as efficient photocatalysts for environmental remediation applications.
