EFFECT OF COBALT AND COPPER ACETATE CO DOPED TO HAVE THE STABILITY OF CALCIUM CARBONATE NANOPARTICLES

physic

In this study, calcium carbonate (CaCO3) nanoparticles co-doped with cobalt (Co) and copper (Cu) acetates were synthesized using a simple precipitation method to improve their stability for various applications. The structural, morphological, and stability properties of the synthesized nanoparticles were thoroughly characterized using a suite of techniques including X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), Fourier-transform infrared spectroscopy (FTIR), and thermal gravimetric analysis (TGA). XRD analysis confirmed the formation of a pure calcite phase with no additional impurities, indicating successful incorporation of the dopants. SEM and TEM imaging demonstrated a uniform distribution of the nanoparticles with well-defined crystalline structures, while FTIR spectra exhibited characteristic peaks corresponding to carbonate and metal-oxygen bonds, confirming the successful doping of Co and Cu ions. TGA results showed enhanced thermal stability of the co-doped nanoparticles compared to pure CaCO3. Stability tests were conducted under various environmental conditions, including acidic and alkaline pH, high temperature, and prolonged exposure to UV radiation. The co-doped nanoparticles exhibited superior stability and resistance to degradation under these conditions compared to their undoped counterparts. This enhanced stability suggests that Co and Cu co-doping significantly improves the performance and extends the shelf life of CaCO3 nanoparticles. These findings highlight the potential of co-doped CaCO3 nanoparticles for practical applications in fields such as pharmaceuticals, cosmetics, and environmental remediation, where stability is crucial for efficacy and longevity.
