ACTIVATED COBALT FERRITE, METHOD FOR PREPARING THEREOF AND METHOD FOR DECOMPOSING CARBON DIOXIDE USING THEREOF

摘要

The present invention provides a kind of cobalt ferrite [(Co_xFe_ (1-x _ 3O_ (4-& delta)) for preparing activation; ), x=0.2~0.9 , & delta; =0.4~0.9], comprising: step manufactures Conjugate ferrite oxalates (Co_xFe_ (1-x) C_2O_4, x=0.2~0.9) reaction retaining wall is by ferrite presoma, cobalt earth-retaining precursor and dicarboxylic acids or its sa Cobalt ferrite oxalates is heat-treated in inactive atmosphere with the step of heat treatment. This method enlivens also being provided with the above-mentioned Conjugate ferrite that enlivens by supply carbon dioxide for Conjugate ferrite manufacture to decompose carbon dioxide, with decomposition. It prepares Conjugate ferrite using a kind of and activates according to the present invention, the cobalt ferrite of activation can economically and safely be made, which can be used in various applications, and there is the cobalt ferrite of activation good carbon dioxide decomposition effect can be obtained, and in addition, efficiency can be enhanced in economy and production technology. ;The 2015 of copyright KIPO submissions
