Here, we successfully developed the undoped, Ni2+, Cu2+, and Zn2+ doped Zirconia nanoparticles (ZrO2 NPs) by a simple co-precipitation method at room temperature and characterized by various physicochemical measurement techniques to investigate their structure, morphology, and sizes of the particles. The bandgap energy values of doped and undoped ZrO2 NPs were estimated using optical absorption spectroscopy and it was found to be in the range of 4.1-4.4 eV. The UV (304-352 nm) and visible (402-4...

This work focuses on the synthesis of undoped and doped lanthanum oxide nanoparticles (La2O3 NPs) by a simple co-precipitation method for the catalytic reduction of 4-nitrophenol (4-NP) using NaBH4 as a reducing agent. Their optical properties, morphologies, structure, chemical compositions and electronic properties were carefully characterized by XRD, FTIR, SEM, TEM, PL and UV–visible absorption spectroscopy. The SEM and TEM images showed various shape morphologies and sizes of the particles. T...
