The so-called colloidal template synthesis has been applied to the preparation of surface-engineered nanoadsorbents. Colloidal microporous organic network nanotemplates (C-MONs), which showed a high surface area (611 m g ) and enhanced microporosity, were prepared through the networking of organic building blocks in the presence of poly(vinylpyrrolidone) (PVP). Owing to entrapment of the PVP in networks, the C-MONs showed good colloidal dispersion in EtOH. MoS precursors were incorporated into the C-MONs and heat treatment afforded core-shell-type C@MoS nanoparticles with a diameter of 80 nm, a negative zeta potential (-39.5 mV), a high surface area (508 m g ), and excellent adsorption performance towards cationic dyes (q =343.6 and 421.9 mg g for methylene blue and rhodamine B, respectively).
所谓的胶体模板合成已被应用于表面工程纳米吸附剂的制备。通过在聚(乙烯基吡咯烷酮)(PVP)存在下使有机构筑块交联，制备了具有高比表面积(611 m g )和增强微孔的胶体微孔有机网络纳米模板(C-MONs)。由于 PVP 被包埋在网络中，C-MONs 在 EtOH 中表现出良好的胶体分散性。MoS 前体被掺入 C-MONs 中，热处理得到了核壳型 C@MoS 纳米粒子，其直径为 80nm，具有负的动电位(-39.5 mV)，高的比表面积(508 m g )，对阳离子染料(亚甲蓝和罗丹明 B 的吸附量分别为 343.6 和 421.9mg g )具有优异的吸附性能。
