A dual-functional indium−organic framework towards organic pollutant decontamination via physically selective adsorption and chemically photodegradation

Abstract

Solvothermal reaction of In(NO3)3∙5H2O and a highly conjugated carboxylate-based tritopic linker, a doubly interpenetrated indium−organic framework of 1 has been deliberately and successfully prepared. As revealed by single-crystal X-ray diffraction, the isolated 1 displays anionic framework and channel-typed interior spaces replete with imidazole rings and free carboxylate oxygens. Due to its uniquely structural features, 1 demonstrates not only selective adsorption of cationic MB concomitant with anionic MO molecules with high selectivity/uptake/adsorption rate, reversibility/recyclability, but also photocatalytic activity to efficiently decompose dyes of MB and MO under the illumination of either UV or visible light due to the consequential MB@1 and MO/1 composites. The new finding of visible light responsive MB@1 and MO/1 composites may open up more applications.
