摘 要：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-CeO2 had a better far infrared emitting property than the tourmaline modified with CeO2, which depended on La enhancing the redox properties of CeO2, leaded to much more oxidation of Fe2+ to Fe3+ in the tourmaline. Based on the results of the water boiling test, it was found that the tourmaline modified with La-doped nano-CeO2 could decrease the consumption of liquefied petroleum gas, which resulted from the tourmaline modified with La-doped nano-CeO2 decreasing the molecular clusters volume of liquefied petroleum gas and combustion-supporting air.
