碳纳米管在500摄氏度以上的高温下可以还原表面包覆的Fe2O3 吗?这是看一篇文章Chinese Journal of Catalysis Vol. 31 No. 7,2010的一篇文章《催化学报》文中制备CNTs/TiO2/Fe,其中生成Fe的制备部分这样写的:The oxidized CNTs
were added to 10 ml solutions with the different Fe(NO3)3·
9H2O concentrations of 0.1, 0.2, and 0.3 mol/L. The mixtures
were stirred for 24 h using a non-magnetic stirrer at
room temperature. After a heat treatment at 773 K, Fe-CNTs
were obtained.有高手知道没有H2或惰性气体保护下可以仅凭碳管的C高温下还原Fe2O3吗?谢谢。另外,生成的Fe有磁性,Fe3O4不也是有磁性的吗?为什么偏要生成单质Fe呢?Fe3O4纳米粒子不是更容易制备吗?
