A novel Ag-doped MOF-like organotitanium polymer (Ag@NH2-MOP(Ti)) was synthesized via a microwave-assisted coordination and polymerization reaction with 2-aminoterephthalic acid (H(2)ATA) and tetra-n-butyl titanate (Ti(OC4H9)(4)), followed by the crystal growth and assembly onto Ag nanopartides (NPs). This Ag@NH2-MOP(Ti) exhibited excellent activity in visible-light driven photocatalytic NO oxidization, much higher than N-doped TiO2 by two times. The NH2-MOP(Ti) absorbed visible lights to generate photoelectrons and holes, accompanied by producing HO center dot and O-2(-) active sites for the subsequent NO oxidation into NO3-. The Ag NPs allowed assembly of NH2-MOP(Ti) polymer favoring light absorbance via multiple reflections and also facilitated photoelectrons transfer to reduce photoelectron-hole recombination, leading to the enhanced photocatalytic activity for NO oxidation and inactivating bacteria. Moreover, it could be used repetitively owing to the high stability. (C) 2015 Elsevier B.V. All rights reserved.
