Synthesis of copper chromite nanocomposites for electrochemical sensor application

The Copper Chromite Nanocomposites (CuCr2O4 Nanoparticles) was synthesised through hydrothermal technique. Several methods, including UV–visible, powder X-ray diffraction and Fourier transform infrared spectroscopy were employed to characterise the produced CuCr2O4 Nanocomposites. Field emission sca...
