Abstract

Hetero photooxidation of sulfide under aqueous conditon is of great important in the green synthesis of sulfoxide. This process require a kinds of solid photocatalysis with the properties of high porosity, water stability as well as the photosensity. Herein, a stable Ir-Zr-MOF materials (compound 1) with high porosity is assemblied from two liner linkers of 2-Phenylquinoline-4-carboxylic acid-Ir(III) complex (Irphen), 4,4'-Stilbenedicarboxylic acid (H2SDC) and Zr6 cluster. 1 is isostrucural to JLU-Liu34 with a composition of [Zr6O4.78(OH)3.22(SDC)3.82(Irphen)0.78TFA2.8]•2.8MeOH and permanent porosity with the BET surface of 1507 m2 g−1. 1 exhibits improved activity for the photocatalytic aerobic oxidation of sulfide to sulfoxide via blue light irridation under aqueous condition. Mechanism studies demonstrate that superoxide radical is the reactive oxygen species in the sulfide photooxidation. 1 can be readily recycled and reused at least 5 times without loss of catalytic activity. This work not only provides a good strategy for assembly of Ir(III) complex into MOFs but also an efficient way for the green synthesis of sulfoxide.
