Facile Synthesis of CeO(2)-LaFeO(3) Perovskite Composite and Its Application for 4-(Methylnitrosamino)-1-(3-Pyridyl)-1-Butanone (NNK) Degradation

A facile and environmentally friendly surface-ion adsorption method using CeCO(3)OH@C as template was demonstrated to synthesize CeO(2)-LaFeO(3) perovskite composite material. The obtained composite was characterized by X-ray diffraction (XRD), fourier transform infrared spectra (FT-IR), field-emiss...

Sumario:A facile and environmentally friendly surface-ion adsorption method using CeCO(3)OH@C as template was demonstrated to synthesize CeO(2)-LaFeO(3) perovskite composite material. The obtained composite was characterized by X-ray diffraction (XRD), fourier transform infrared spectra (FT-IR), field-emission scanning electron microscopy (FE-SEM), transmission electron microscopy (TEM), thermo-gravimetric analysis and differential scanning calorimetry (TG-DSC), N(2) adsorption/desorption isotherms and X-ray photoelectron spectra (XPS) measurements. The catalytic degradation of nitrosamine 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanone (NNK) was tested to evaluate catalytic activity of the CeO(2)-LaFeO(3) composite. Much better activity was observed for the CeO(2)-LaFeO(3) composite comparing with CeO(2) and LaFeO(3). These results suggested that perovskite composite materials are a promising candidate for the degradation of tobacco-specific nitrosamines (TSNAs).
