英文摘要	Sulfur dioxide (SO2) emissions from diesel exhaust pose a serious threat to the environment and human health. Thus, desulfurization technology and the performance of desulfurization materials must be improved. In this study, MnO2 was modified with various alkali metal ions using the impregnation method to enhance its SO2 capture performance. The composites were characterized intensively by scanning electron microscopy, energy-dispersive X-ray spectroscopy, X-ray diffraction spectroscopy, and Brunauer-Emmett-Teller theory. The SO2 capture performance of these composites were measured via thermogravimetry, and the effect of doping with alkali metal ions on the SO2 capture performance of MnO2 was investigated. Results showed that the SO2 capture performance of MnO2 could be enhanced by doping with alkali metal ions, and the MnO2 composite doped with LiOH (2.0 mol/L) had the best SO2 capture capacity (124 mg(SO)(2)/g(Material)), which was 18% higher than that of pure MnO2. Moreover, the type and concentration of alkali metal ions had varying effects on the SO2 capture performance of MnO2. In our experiment, the SO2 capture performance of the MnO2 doped with NaOH, LiCl, Na2CO3, K2CO3, and Li2CO3 composites were worse than that of pure MnO2. Therefore, the influences of the type and concentration of alkali metal ions to be doped into desulfurization materials must be considered comprehensively.
