In this work, we present a synthesis of the Ag nanoparticle decorated on the hollow porous organic nanospheres (Ag@OH-HPONs) by simple combination of the Lewis acid–base interaction mediated self-assembly and followed impregnation reduction method, in which the OH-HPONs were prepared via a Friedel-Crafts reaction by using 1,4benzenedimethanol as monomer. Then, the OH-HPONs is modified to convert the OH group to the COOH group. Owing to the abundant carboxyl groups on the wall of the COOH-HPONs, the Ag nanoparticles can be successfully decorated on the COOH-HPONs to produce of Ag@COOH-HPONs via electrostatic (ion‐dipole)interactions with [Ag(NH3)]2+ following by an in-situ reduction of PVP(polyvinylpyrrolidone). The obtained Ag@COOH-HPONs exhibit the high catalytic activities for the dye degradation. This approach for fabricating the metal decorated porous organic polymers may provide guidance for the new type of the morphological controlled catalysts for practical applications.
