摘要:以价廉的Fe(NO3)3·9H2O和H3PO4为原材料,通过蒸发结晶的方法制备出高纯FePO4·2H2O,再将FePO4·2H2O焙烧得到FePO4,将其与电池级Li2CO3、葡萄糖混合,行星球磨后,在600 ℃下氮气氛围的管式炉中焙烧,合成电池的正极材料LiFe...
The Chemistry and Kinetic Behaviour of Fe(III) Reactions with Wood Model Compounds and Pine WoodThe reactions of Fe(III) compounds such as Fe(NO3)3 with wood constituents has been investigated by using both simple model compounds and wood flour. After an initial very rapid adsorption Fe3+ ...
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...
