Zinc vanadate micro/ nano materials are multifunctional, with good stability, high chemical activity, and high visible light transmittance. The properties and application fields of the materials are closely r elated to their morphology and size. Therefore, controllable synthesis of zinc vanadate micro/ nano materials is particularly important. In this study, zinc vanadate with nano disk, nanorod and micron flower structure was prepared by SDS assisted hydrothermal method with sodium metanovadate and zinc acetate as raw materials. The effect of surfactant, pH, hydrothermal temperature and time on the morphology of zinc vanadate were investigat ed. The electrochemical properties of zinc vanadate with different morphologies were studied by preparing electrodes with different morphologies as active substances. The results show that the optimal dosage of SDS is 8 %, and lower pH is favorable for the formation of discoid structure, while higher pH is favorable for rod-like structure. When the hydrothermal temperature is raised to 180 °C, the lamellar zinc vanadate self-assembles to form micron flower structure. Compared to the nano-disk and nanorod morphology, zinc vanadate with flower morphology has the best electrochemical properties, and its rate capability is 64%. After 1 000 cycles, the capacitance retention rate of the micron flower is still 86% of the initial value. Therefore, zinc micron flower vanadate is a potential material for supercapacitors.
