Abstract

Developing luminescent metal-organic frame-works(MOFs)capable of high-efficiency Fe3+sensing has aroused great attraction in the fields of biology,chemistry,etc.However,previous solvothermal methods are limited by organic solvent usage,time consuming,high pressure,and high-energy consumption.Herein,we propose the waste-to-MOF strategy towards the scale-up production of La-MOF nanoparticles through the ball milling of recycled poly(-ethylene terephthalate)(PET)bottles and La(NO3)3·6H2O.PET goes on alkaline hydrolysis to form 1,4-benzenedicar-boxylic acid sodium salt(Na2BDC)and ethylene glycol by ball milling.Subsequently,BDC reacts with La3+to form La-MOF.The as-prepared La-MOF crystal nanoparticles possess a rod-like morphology with the size of few hundred nanometers.Additionally,La-MOF nanoparticles display high selectivity and sensitivity for Fe3+detection.The quenching constant and limit of detection are 5.29 × 103(mol·L-1)-1 and 0.147 pmol·L-1,respectively,thus sur-passing many advanced Fe3+sensors.According to the result of density functional theory,the high Fe3+detection per-formance of La-MOF is related to the complexing of Fe3+with La-MOF,which leads to the gradual dissociation of the coordination bond between terephthalic acid and La3+.It is anticipated that the mechanochemistry milling-based waste-to-MOF strategy provides a new platform for the massive production of functional MOFs in a green manner.
