Effect of Tourmaline Modified with La-Doped Nano-CeO<,2> on Consumption of Liquefied Petroleum Gas
Tourmaline was modified with cerous nitrate and lanthanum nitrate by coprecipitation method. Through characterization by differential thermal analysis, transmission electron microscopy, X-ray diffraction, and Fourier transform infrared spectroscopy, it was found that the tourmaline modified with La-doped nano-CeO<,2> had a better far infrared emitting property than the tourmaline modified with CeO<,2>, which depended on La enhancing the redox properties of CeO<,2>, leaded to much more oxidation of Fe<2+> to Fe<3+> in the tourmaline. Based on the results of the water boiling test, it was found that the tourmaline modified with La-doped nano-CeO<,2> could decrease the consumption of liquefied petroleum gas, which resulted from the tourmaline modified with La- doped nano-CeO<,2> decreasing the molecular clusters volume of liquefied petroleum gas and combustion- supporting air.
