Herein, we report the methods adopted for the syntheses of nano-scale CeO2 materials by wet chemical routes (solution combustion, hydrothermal, and precipitation by NH4OH and mixture of NH4HCO3 and NH4OH) and their experimental results supported by differential thermal analysis, X-ray diffraction, field-emission scanning electron microscopy energy dispersive X-ray analysis, Fourier transform infrared spectroscopy, and near-infrared characterization techniques. The nano-scale CeO2 materials were obtained through wet chemical and simple calcination methods in a single-step process. The thermal profile of precursor salt ((NH4)2Ce(NO3)6) reveals ~72% of weight loss in the temperature ranges from 30 to 800°C, whereas the different as-obtained CeO2 materials showed ~3-13% of weight loss indicating the formation of cubic nanostructured CeO2 materials, as evidenced from XRD patterns. All of the pure materials obtained in a single step crystallized in cubic nanostructured CeO2 phase with the average crystalline sizes in the range of 3–28 nm. The morphology of the combustion obtained CeO2 materials exhibits spherical-shaped fine particles with moderate agglomeration. The as-obtained CeO2 materials can be used in the solar reflective and color pigment applications as it shows remarkably high NIR reflectance in the NIR region, 750–2500 nm compared to other binary oxides.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
