•FeO/CdO nanocubes prepared by hydrothermal method.•1,2-dichlorobenzene chemi-sensor by electrochemical method.•Chemi-sensor exhibits the lowest LOD in short response time.•Practically analyzed the real environmental samples.•Effective chemi-sensor for environmental field.
In this approach, we report the assembly of a dynamic, high sensitive, selective and reproducible 1,2-dichlorobenzene (1,2-DCB) chemi-sensor development based on solvothermally prepared nanocubes (NCs) of FeO/CdO. The synthesized FeO/CdO NCs was exhibited as an excellent electron mediator during the sensing performance of 1,2-DCB in aqueous medium and this research work was executed by electrochemical method. The morphological, optical, elemental, and structural characterization of synthesized NCs were investigated by various conventional techniques such as FTIR, UV–vis, FESEM, XPS, EDS, and XRD. NCs were used to fabricate glassy carbon electrode (GCE) with nafion conducting binder. The sensitivity of proposed chemi-sensor was estimated from the slope of calibration curve attained as current versus concentration of 1,2-DCB relation. It was introduced a reliable future sensitive sensor development using FeO/CdO NCs by electrochemical approach for the probable detection of toxic 1,2-DCB and other environmental carcinogenic chemicals for the safety of environmental and health care fields.
