Aralia elata leaf extracts synthesize ZnO-based nanoclusters and their dye removal applications

/g. AE-ZnONCs could rapidly and efficiently adsorb methylene blue (MB) and sunset yellow (SY) dyes from water; The XRD and SEM analyses have confirmed that the AE-ZnONCs material after the dye adsorption experiment still maintains a stable layered morphology structure, and the hydrothermally synthesized AE-ZnONCs also possesses structural stability. The MB adsorption process follows second-order kinetics and adheres to the Freundlich-type multi-layer adsorption isotherm model. SY adsorption process follows intraparticle diffusion model kinetics and adheres to the Freundlich-type multi-layer adsorption isotherm model. The green hydrothermal preparation method for functionalized zinc oxide promoted advantages such as abundant raw materials, high cost-effectiveness, environmental friendliness, controllable parameters, simple equipment, and easy operation, with broad application prospects.
