| 摘 要： | 为降低卷烟烟气中的氮氧化物(NOx),采用TG、XRD、氮吸附和TEM等方法测定了LaFeO3钙钛矿型复合金属氧化物——LaFe0.85Pd0.05Cu0.1O3的热稳定性、比表面积、粒子的形状与大小,以及对NO的分解催化活性,并以添加于造纸法再造烟叶中的形式,考察了该氧化物对卷烟烟气中NOx等有害成分的影响。结果表明:于700℃下焙烧2h,该氧化物的比表面积为17.24m2/g,平均粒径50nm,具有较高的NO分解催化活性;与对照相比,含1.5%该复合金属氧化物的卷烟烟气中NOx含量降低13.0%,比焦油多降低约9百分点。

| Abstract: | In order to reduce the NOx in mainstream cigarette smoke,the thermal stability,specific surface area,shape,size,catalytic activity for NO decomposition of nanoparticulate perovskite oxide(LaFe0.85Pd0.05Cu0.103) were tested by thermal gravity(TG),X-ray diffraction(XRD),nitrogen adsorption,and transmission electron microscope(TEM).By adding it into paper-making process reconstituted tobacco,the effects of LaFe0.85Pd0.05Cu0.1O3 on NOx and other harmful components in cigarette smoke were investigated.The result... |
