An efficient electrochemical sensing and catalysis platform based on Cu–Ni alloy is developed. The Cu–Ni alloy (CN) are synthesized using ultrasonic aided thermal annealing process. The synthesized Cu–Ni nanostructures are thoroughly characterized for its crystallinity, morphology and topography. For the electrochemical sensing, the resorcinol is chosen as analyte and for catalyst assisted chemical degradation process, methylene blue is selected as an analyte. Upon electrochemical sensing investigation, Cu–Ni alloy-based sensor exhibited superior sensitivity of 7.9472 μAμM−1cm−2 and current responses are linear over the concentration range from 0.01 to 5.59 μM. The limit of detection (LOD) and limit of quantification (LOQ) of the sensor is estimated to be 5.24 nM and 0.0175 μM. The sensor is successfully tested for real time environmental samples. In the catalyst assisted chemical degradation of the methylene blue dye investigation, our catalyst Cu–Ni alloy accelerated the degradation of methylene blue in 9 min.
The binary nanomaterials and graphitic carbon-based hybrid has been developed as an important porous nanomaterial for fabricating electrode with applications in non-enzymatic (bio) sensors.
