The current research focuses on the development of Ag-ZnO heterostructures through a "bottom-up" approach involving the assembly and extraction of Aloe barbadensis Miller gel. These heterostructures composed of metals/semiconductor oxide display distinct and notable optical, electrical, magnetic, and chemical properties that are not found in single constituents and also exhibit photocatalytic applications. These synthesized heterostructures were characterized by XRD, FTIR, SEM, and UV-visible spectroscopy. The high peak intensity of the Ag/ZnO composite shows the high crystallinity. The presence of Ag-O, Zn-O, and O-H bonding is verified using FTIR analysis. SEM analysis indicated the formation of spherical shapes of Ag/ZnO heterostructures. The Zn, O, and Ag elements are further confirmed by EDX analysis. Ag-ZnO heterostructures exhibited excellent photocatalytic activity and stability against the degradation of tubantin red 8BL dye under visible light irradiation.
当前的研究聚焦于通过一种“自下而上”的方法来开发银-氧化锌异质结构，该方法涉及库拉索芦荟凝胶的组装和提取。这些由金属/半导体氧化物组成的异质结构展现出独特且显著的光学、电学、磁学和化学性质，这些性质在单一成分中并不存在，并且还具有光催化应用。这些合成的异质结构通过X射线衍射（XRD）、傅里叶变换红外光谱（FTIR）、扫描电子显微镜（SEM）和紫外可见光谱进行了表征。银/氧化锌复合材料的高峰强度表明其具有高结晶度。通过傅里叶变换红外光谱分析验证了银-氧、锌-氧和氧-氢键的存在。扫描电子显微镜分析表明形成了银/氧化锌异质结构的球形。能谱分析（EDX）进一步证实了锌、氧和银元素的存在。银-氧化锌异质结构在可见光照射下对图班汀红8BL染料的降解表现出优异的光催化活性和稳定性。
