Abstract

Herein we report the solid synthesis, structural characterization, magnetic behavior, and electrochemical sensing properties of Mn0.4Cd0.6Cr2S2Se2. Single-crystal X-ray diffraction analysis showed that Mn0.4Cd0.6Cr2S2Se2crystallizes in a spinel-type structure. Powder X-ray diffraction patterns and Rietveld refinement data revealed that this selenide phase is consisted of cubic Fd3m space group. Magnetic field cooling (MFC) measurements indicated an enhancement in ferromagnetic interactions relative to the ferrimagnetic compound Mn0.4Cd0.6Cr2S4, which can be attributed to the substitution of sulphur by selenium. The electrochemical response of modified glassy carbon electrodes with Mn0.4Cd0.6Cr2S2Se2was increased, the peak current is increased 4-fold, from 20.15 μA to 83.52 for GC, and GC-Mn0.4Cd0.6Cr2S2Se2respectively by differential pulse voltammetry, and thus it could be used to design an electrochemical sensor to quantify nitrocompounds, considered pollutants and toxic agents for humans, plants, and animals.
