N-methylimidazolium-functionalized pollen-like mesoporous silica (MI-PLMS) was successfully prepared by a simple and convenient soft-templating hydrothermal method for the first time. MI-PLMS sub-microspheres possess multi-shell hollow architecture with a relatively high surface area of 400 m² g⁻¹. Owing to its facile synthesis route and abundant surface functional groups, MI-PLMS could be a potential candidate material in a variety of applications such as drug delivery, water treatment, and catalysis. To evaluate its adsorption performance, the adsorption capacity of hexavalent chromium by MI-PLMS was monitored. Nonlinear kinetics and isotherms models were used for choosing an appropriate mechanism for hexavalent chromium adsorption on the adsorbent and the maximum monolayer adsorption capacity of adsorbate was found to be 274.01 mg g⁻¹ according to the Langmuir isotherm.

首次通过简单方便的软模板水热方法成功制备了N-甲基咪唑鎓官能化的花粉状介孔二氧化硅（MI-PLMS）。MI-PLMS亚微球具有多壳空心结构，具有400 m ²  g ^-1的较高表面积。由于其合成路线简便，表面官能团丰富，MI-PLMS可能在药物输送，水处理和催化等多种应用中成为潜在的候选材料。为了评估其吸附性能，通过MI-PLMS监测了六价铬的吸附容量。使用非线性动力学和等温线模型来选择合适的六价铬在吸附剂上的吸附机理，并且根据Langmuir等温线，发现被吸附物的最大单层吸附容量为274.01 mg g ^-1。
