英文摘要	we report a new hydroxyl functionalized microporous organic polymer (mopoh) based on the polymerization of catechol with terephthalaldehyde using phenolic resin-inspired chemistry. this catechol-decorated material, with surface area of 874 m(2) g(-1) and micro, mesopores, facilitates the immobilization and dispersion of pd nanoparticles (nps) on the polymer matrix. the surface area of the created composite (pd@mopoh) decreases to 419 m(2) g(-1) and the pore size distribution is narrowly distributed at 1.54 nm due to the filling of mesopores. the co2 capture capacities for mopoh and pd@mopoh at 273 k and 1 bar are 13.4 and 9.2 wt%, respectively. the resultant pd nps are crystalline and uniform with a mean diameter of 4.8 nm. the well-dispersed pd@mopoh exhibits excellent catalytic activity toward the model reduction of 4-nitrophenol into 4-aminophenol. significantly, nearly no pd leaching is detected during the catalytic cycles, showing active and durable nature of the heterogeneous nanocatalyst.
