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 2 g −1 ) 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 2 precursors were incorporated into the C‐MONs and heat treatment afforded core–shell‐type C@MoS 2 nanoparticles with a diameter of 80 nm, a negative zeta potential (−39.5 mV), a high surface area (508 m 2 g −1 ), and excellent adsorption performance towards cationic dyes ( q max =343.6 and 421.9 mg g −1 for methylene blue and rhodamine B, respectively).
