Nitrogen‐Rich Porous Organic Polyamines for Stabilization of Highly Dispersed Metal Nanoparticles and Catalytic Application

Abstract Nitrogen‐rich triazine‐based porous organic polyamines (POPa) synthesized via a one‐step polycondensation of melamine and 4,4′,4′′‐(1,3,5‐triazine‐2,4,6‐triyl)tribenzaldehyde is employed to synthesize Au and Pd nanoparticles well‐dispersed on POPa. The as‐prepared POPa‐supported Au NPs and Pd NPs (AuNPs@POPa, PdNPs@POPa) with a narrow size distribution show remarkable catalytic activity for the reduction of nitrobenzene compounds and organic dyes and the Suzuki–Miyaura coupling reaction, respectively. Benefitting from POPa the AuNPs@POPa and PdNPs@POPa catalysts can be readily recovered and reused almost without loss of activity. The nitrogen‐rich porous organic polyamines provide great opportunities to prepare functional metal nanocatalysts with potential in the heterogeneous catalysis field.
