The influence of different solvents, including aqueous and nonaqueous types, on the physicochemical properties of VO nanostructures was thoroughly investigated. Various characterization techniques, such as XRD, XPS, FTIR, Raman spectroscopy, UV-vis DRS, SEM, TEM, and BET, were employed to analyze the obtained materials. Additionally, the adsorption properties of the synthesized VO nanostructures for methylene blue were examined, and kinetic parameters of adsorption were calculated. The results demonstrate that the morphology of the obtained crystals can be finely controlled by manipulating water concentration in the solution, showcasing its profound impact on both the structural characteristics and adsorption properties of the nanostructures. Furthermore, the structural changes of the resulting VO material induced by solvents show strong impacts on its photocatalytic properties, making it a promising photocatalyst.
深入研究了包括水性和非水性类型在内的不同溶剂对VO纳米结构物理化学性质的影响。采用了各种表征技术，如XRD、XPS、FTIR、拉曼光谱、紫外可见漫反射光谱、SEM、TEM和BET，对所得材料进行分析。此外，还研究了合成的VO纳米结构对亚甲基蓝的吸附性能，并计算了吸附动力学参数。结果表明，通过控制溶液中的水浓度，可以精细地控制所得晶体的形态，这表明其对纳米结构的结构特征和吸附性能都有深远影响。此外，溶剂诱导的所得VO材料的结构变化对其光催化性能有强烈影响，使其成为一种有前途的光催化剂。
