A method of preparing magnesium cobalt metal composite oxides based on activated magnesium oxide, involving a method of preparing metal composite oxides.
In the first step, magnesium-cobalt metal composite oxides are prepared by using active magnesium oxide and cobalt chloride as raw materials
In the second step, the active magnesium oxide is dissolved in water to form a hydrated magnesium oxide complex;
In the third step, cobalt chloride is mixed into an aqueous solution of a certain concentration and dropped into a hydrate magnesium oxide complex solution;
In the fourth step, MG2COO4 and MGCO2O4 mg-co composite metal oxides were obtained by filtering, washing, drying and calcining the emulsion.
Using active magnesium oxide and cobalt chloride as raw materials to prepare magnesium-cobalt metal composite oxides, the phenomenon of metal ion complex copolymerization in aqueous solution was utilized to form metal ion water and hydroxyl copolymer without any additives, simple. The prepared MG2COO4 and MGCO2O4 mg-co composite metal oxides have bimetallic centers and can be used as catalysts or supports for some organic reactions.
