* 在铁系元素中,只有铁能形成稳定的氧化值为+3的简单盐,常见Fe(Ⅲ)的强酸盐,如Fe(NO3)3·6H2O、FeCl3·6H2O、Fe2(SO4)3·12H2O等都易溶于水,在这些盐的晶体中含有[Fe(H2O)6]3+,这种水合离子也存在于强酸性(pH=0左右)溶液中。 由于Fe(OH)3比Fe(OH)2的碱性更弱,所以Fe(Ⅲ)盐较Fe(Ⅱ)盐易...
与直接碳化得到的 Co@C 催化剂相比,制备的 Co3O4/Al2O3-x 催化剂具有更好的 FTS 活性和更低的 CH4 选择性。 不同铝源的 Co3O4/Al2O3-x 催化剂表现出不同的 FTS 性能,其中,使用Al(NO3)3⋅9H2O作为铝源的催化剂性能最好,具有更强的金属-载体相互作用、Co 颗粒尺寸较小且拥有更多的活性位点数量...
