Unusual hexa-nuclear cadmium cluster functionalized phosphomolybdate as effective photoelectrochemical sensor for trace Cr(Ⅵ)detection
文献摘要：
Photo-assisted electrochemical technique provides a promising approach towards carcinogen chromium(Ⅵ)detection,which requires reasonable catalyst design.Herein,an unusual hexa-nuclear cadmium cluster functionalized reductive phosphomolybdate hybrid as photo-electrochemical sensor was designed and synthesized with formula of{[Cd(H2O)2]2[Cd(btmbp)]2}{Cd(P4Mo6O31H7)2}·20H2O(1)(btmbp=4,4'-bis((1H-1,2,4-triazol-1-yl)methyl)biphenyl),in which the photoactive hexa-nuclear{Cd6}clusters cooperated with reductive phosphomolybdate[P4Mo6O31]12-endow the material with wide light absorption and remarkable redox activity,thus achieving efficient photo-assisted electrochemical Cr(Ⅵ)detection performance.Under visible-light assistance,the detection limit(LOD)and sensitivity of Cr(Ⅵ)is 4.17 nmol/L(0.225 ppb)and 226.32 μA L/μmol,which is apparently superior to the performance without photo-assistance(6.25 nmol/L and 106.95 μA L/μmol)and far satisfies the demands of world health organization(WHO)for potable water(50 ppb).Moreover,compound 1 showed prominent Cr(Ⅵ)detection performance in practical water samples together with remarkable anti-interference capacity and good electrochemical durability.This work provides an important guidance for designing efficient polyoxometalate-based crystalline sensors for Cr(Ⅵ)detection.
