FT-IR spectra of a Co3O4@Glu and b Co3O4@Glu/TSC nanoparticles. The FTIR spectrum result showed that the surface adsorption of functional groups on nanoparticles. The XRD patterns of the synthesized Co3O4@Glu/TSC NPs (c). In the XRD spectrum, the peaks at 2θ values of 85.34°, 82.77°, 81.04°, 72.96°, 68.48°, 60.39°, 44.33°, 37.92°, and 22.07° belong to the crystal structure of Co3O4@Glu/TSC NPs
