Facile preparation of a hierarchically porous metal–organic nanocomposite with excellent catalytic performance

Abstract

Herein, we report a strategy to prepare a hierarchical micro–meso–macro porous metal–organic nanocomposite, hpCuL (L = 2,4,6-tris(3,5-dicarboxylatephenylamino)-1,3,5-triazine), using a facile gel-aging process. The effect of pH values and aging time on the growth morphologies was monitored. This 3-D material, comprised of continuous metal–organic framework nanocrystallines serving as pore walls, exhibits high catalytic activity and stability towards the reduction of 4-nitrophenol by NaBH₄ in water.
