specific Embodiment approach 1
[0018] Specific embodiment one: a kind of in-situ method for preparing ferric oxide / carbon / nano-graphite microsheet nano-composite material described in this embodiment is carried out according to the following steps:
[0019] 1. Add ferric salt, ferrous salt, expanded graphite and carbon-based compound to the water containing reaction additives, mix and ball mill with a ball mill for 2h to 8h to obtain a well-dispersed composite dispersion system;
[0020] Fe in the ferrous salt 2+ Fe in ferric salt 3+ The molar ratio is 0.5:1; the mass ratio of the expanded graphite to the ferric salt is (0.3~1.5):1; the mass ratio of the carbon-based compound to the ferric salt is (0.2~1.0) : 1; the mass ratio of the volume of the water to the ferric salt is (50-200) mL: 1g; the volume ratio of the reaction aid to water is (0.01-0.04): 1;
[0021] 2. Mix the composite dispersion system with a substance that can be decomposed by heat to produce hydroxide ions and place it in a closed high-...
specific Embodiment approach 2
[0024] Specific embodiment two: the difference between this embodiment and specific embodiment one is that the carbon-based compound described in step one is one or several of chitosan, carboxymethyl chitosan and water-soluble chitosan mixture of species. Others are the same as in the first embodiment.
specific Embodiment approach 3
[0025]Embodiment 3: The difference between this embodiment and Embodiment 1 or 2 is that the reaction aid described in step 1 is one of glacial acetic acid, dilute hydrochloric acid and dilute nitric acid or a mixture of several of them. Others are the same as in the first or second embodiment.
