Effect of morphology of dispersed nano CeO2 on far infrared emission property of natural tourmaline.
Dispersed nano CeO2 successfully grew on the surface of natural tourmaline powders by a precipitation method. The results of Fourier transform infrared spectroscopy (FTIR) showed that CeO2 (111) nanospots could apparently enhance the far infrared emission property of tourmaline in relation to CeO2 nanoparticles. This is the first report regarding the effect of the morphology of nano CeO2 on the far infrared emission property of natural tourmaline. The results of the characterization by transmission electron microscopy (TEM) X ray diffraction (XRD) and X ray photoelectron spectroscopy (XPS) showed that CeO2 (111) nanospots have much more chemisorbed oxygen than CeO2 nanoparticles, which is beneficial to the unit cell volume shrinkage of tourmaline, thus increasing its far infrared emissivity.
