Synthesis of biphenyl bridged dendritic mesoporous organosilica with extremely high adsorption of pyrene

Abstract

The development of functional materials with high adsorption performance towards polycyclic aromatic hydrocarbons (PAH) such as pyrene is important to environment protection and human health. Herein, for the first time, we report the synthesis of biphenyl bridged dendritic mesoporous organosilica nanoparticles (BDMONs) by using a co-solvent-assisted approach. It is demonstrated that the biphenyl bridged groups in nano-adsorbents play an important role on their adsorption performance for PAH with multiple fused aromatic rings. Compared to the counterpart with a phenyl bridged group, BDMONs exhibit lower adsorption energy towards pyrene and three times higher adsorption capacity (~2.5 g/g), with nearly all the porous space utilized for adsorption.
