Abstract

Ag@MOF(Ag) nano-composites were fabricated through one-pot facile reflux reaction from the raw materials of AgNO3 and 2-aminoterephthalic acid, and were then characterized through SEM, TEM, XRD, XPS, and FTIR, which showed a high fluorescence quantum yield (10.6%) and exhibited outstanding selectivity and excellent sensitivity for 2,4,6-trinitrophenol (TNP) over a concentration range of 1-29μM in water. The fluorescence quenching mechanism may be attributed to hydrogen-bonding interactions and resonance energy transfer.
