摘要: 采用水热法，以NaBF4作为氟源，通过调节pH值，制备三维网状堆叠的分级CdOHF纳米结构。结果表明，不同的pH值和反应时间使得CdOHF具有一维纳米带、纳米带编织的二维网状结构和网叠的三维层次结构的可调结构变化。发现产物对阳离子有机染料展现出较强的选择性，对孔雀石绿(MG)的理论最大吸附量达48.31 mg/g。XRD和FTIR证明该吸附过程是物理吸附，符合准二阶动力学方程和Langmuir等温吸附方程。
Abstract: Using NaBF4 as fluorine source, a hydrothermal method was used to prepare the nanonets-stacked hierarchical CdOHF nanostructures by varying pH value. The results showed that different pH values and reaction times made the CdOHF feature adjustable structural variations with 1D nanobelts, nano-belt-woven 2D nets and net-stacked 3D hierarchical structures. The adsorption properties of the CdOHF were investigate and exhibited a strong selectivity for cationic organic dyes. The theoretical maximum adsorption of graded structure CdOHF on MG was calculated to reach 48.31 mg/g. XRD and FTIR results indicate the adsorption process was physical adsorption. The adsorption process of CdOHF on Malachite Green conforms to the quasi second-order dynamic equation and Langmuir iso-thermal adsorption equation.
