Description
Technical field
The present invention relates to a kind of method that solid phase prepares Cadmium Sulfide/oxidized graphite composite material, belong to field of nano material preparation.
Background technology
In recent years, the physics-chem characteristic of uniqueness that has due to itself of nano material and receive the extensive concern of researcher.Cadmium Sulfide, as a kind of very important semiconductor nano material, because it has the character such as special optical, electrical, thermal and magnetic, and shows huge application prospect in fields such as light emitting semiconductor device, nonlinear optical material, photochemical catalysis.But cadmium sulfide nano material, due to small-size effect and surface effects etc., makes it very easily reunite in preparation process, and then have influence on its performance and practical application.Therefore, people have employed multiple method to slow down the reunion of cadmium sulfide nano material.Wherein, template is adopted can effectively to stop it to reunite as carrier.Graphene is owing to having large specific surface area and high chemical stability and causing the great interest of people, and graphite oxide is regarded as the Graphene of hydroxyl and carboxyl-functional.Cadmium Sulfide and graphite oxide compound as carrier, can be stoped the reunion of cadmium sulfide nano material by the specific surface area that graphite oxide is large for this reason effectively.
At present, the method preparing Cadmium Sulfide and graphene composite material comprises hydrothermal method and microwave method etc., but these methods relate to experiment condition harshness, the high deficiency of energy consumption, and thus exploitation is a kind of simply, high yield, eco-friendly synthetic method are still very urgent.Rare earth chemical method have simple to operate, cost is low, output is high and advantages of environment protection, has become a kind of effective ways of nano materials.
Summary of the invention
The object of the present invention is to provide a kind of solid phase to prepare the method for Cadmium Sulfide/oxidized graphite composite material, is utilize graphite oxide for template employing rare earth chemical reaction is to prepare Cadmium Sulfide/oxidized graphite composite material.The method overcome cadmium sulfide nano material and serious agglomeration phenomenon occurs in preparation process, and achieve the compound of graphite oxide and Cadmium Sulfide.
The invention discloses a kind of method that solid phase prepares Cadmium Sulfide/oxidized graphite composite material.Method of the present invention grinds with metal cadmium salt, graphite oxide the rare earth chemical preparation reacting and then realize Cadmium Sulfide/oxidized graphite composite material together with thioacetamide.
The method that the present invention prepares Cadmium Sulfide/oxidized graphite composite material using graphite oxide as template solid phase is simple to operate, do not use solvent, high yield, cost low, and the preparation for graphite oxide based composites provides a kind of new thinking.
