A multi-functional Cd(II)-based coordination polymer for the highly sensitive detection of nitrofurazone and photocatalytic efficiency of Rhodamine B

Abstract

A new Cd(II)-based metal–organic framework, namely {[Cd(H3L)(bb)(μ2-H2O)]·H2O}n (1) (H5L = 3,5-bis(3,4-dicarboxylphenoxy)benzoic acid and bb = 4,4′-bis(imidazolyl)biphenyl), was hydrothermally prepared. 1 tackled effectively photocatalytic capacity to defeat the dye Rhodamine B (Rh B). Furthermore, The sensing experiments indicated that the 1 displayed sensitive and selective sensing against nitrofurazone (NFZ) with limit of detection (LOD) of 1.34 ppm and Ksv value of 1.33 × 103 M−1. The plausible mechanism worked by 1 for the catalytic degradation toward Rh B was conducted and suggested by the LC-MS studies.
