Zusammenfassung: | The invention relates to a Zn (at) ZnO/SiC/spherical attapulgite material and application thereof.The preparation method comprises the following steps that A, SiC and zinc sulfate are taken and mixed, absolute ethyl alcohol is added, then an ethanol solution of 1% polyethylene glycol 400 is dropwise added in the stirring state, and after stirring is conducted for half an hour, a suspension is obtained; b, dropwise adding ammonia water into the suspension, uniformly stirring, standing at room temperature for 4-8 hours, centrifuging, then adding ionized water to clean a centrifugal precipitate, and then performing vacuum drying for 2-4 hours to obtain a ZnO/SiC intermediate; c, introducing hydrogen into the ZnO/SiC intermediate at 280-320 DEG C for partial reduction to obtain Zn/ZnO/SiC intermediate powder; and D, in a hot air environment, taking attapulgite particles, spraying water to wet the attapulgite particles, then gradually adding the Zn/ZnO/SiC intermediate powder, uniformly mixing, and drying, thereby |
