Abstract

A method for preparing mesoporous copper oxide (CuO) includes providing a copper composition including copper (Cu), phenanthroline, and a Schiff base, combining the copper composition with a sodium salt to provide a salt mixture, and calcining the salt mixture to provide the mesoporous CuO. The mesoporous copper oxide has an ordered structure and a diameter ranging from about 0.5 μm to about 3 μm.

First claim

1 . A method for preparing mesoporous CuO, comprising:
providing a copper (Cu) composition including copper (Cu), phenanthroline, and a Schiff base; combining the copper (Cu) composition with a NaX salt to provide a salt mixture; and calcining the salt mixture to provide the mesoporous CuO, wherein X is selected from the group consisting of Cl, Br, and NO 3 ;
wherein the phenanthroline has the structure;

and
wherein the Schiff base has the structure:

2 . The method as recited in claim 1 , wherein the copper (Cu) composition is prepared by a method comprising:
dissolving CuBr 2 ·4H 2 O in an alcohol to form a first mixture; dispersing phenanthroline in an alcohol to form a second mixture; combining the first mixture and the second mixture to form a third mixture; and adding a Schiff base ligand to the third mixture to provide the copper (Cu) composition.

3 . The method as recited in claim 1 , wherein the salt mixture is calcined until a temperature ranging from about 500° C. to about 600° C. is achieved.

4 . Mesoporous CuO prepared according to the method of claim 1 .

5 . The mesoporous CuO of claim 4 , wherein the mesoporous CuO has a diameter ranging from about 0.5 μm to about 3 μm.

6 . A method for preparing mesoporous CuO, comprising:
providing a copper (Cu) composition including copper (Cu), phenanthroline, and a Schiff base; combining the copper (Cu) composition with a NaX salt to provide a salt mixture; calcining the salt mixture until a temperature ranging from about 500° C. to about 600° C. is achieved, to provide the mesoporous CuO, wherein X is selected from the group consisting of Cl, Br, and NO 3 ; wherein the phenanthroline has the structure:

and
wherein the Schiff base has the structure:

7 . The method as recited in claim 6 , wherein the copper (Cu) composition is prepared by a method comprising:
dissolving CuBr 2 ·4H 2 O in an alcohol to form a first mixture; dispersing phenanthroline in an alcohol to form a second mixture; combining the first mixture and the second mixture to form a third mixture; and adding a Schiff base ligand to the third mixture to provide the composition.

8 . Mesoporous CuO prepared according to the method of claim 7 .

9 . The mesoporous CuO of claim 8 , wherein the mesoporous CuO has a diameter ranging from about 0.5 μm to about 3 μm.

10 . A method for preparing mesoporous CuO, comprising:
providing a copper (Cu) composition including copper (Cu), phenanthroline, and a Schiff base; combining the copper (Cu) composition with a NaX salt to provide a salt mixture; calcining the salt mixture to provide the mesoporous CuO, wherein X is selected from the group consisting of Cl, Br, and NO 3 , and the mesoporous CuO has a diameter ranging from about 0.5 μm to about 3 μm; wherein the phenanthroline has the structure:

and
wherein the Schiff base has the structure:

11 . The method as recited in claim 10 , wherein the copper (Cu) composition is prepared by a method comprising:
dissolving CuBr 2 ·4H 2 O in an alcohol to form a first mixture; dispersing phenanthroline in an alcohol to form a second mixture; combining the first mixture and the second mixture to form a third mixture; and adding a Schiff base ligand to the third mixture to provide the copper (Cu) composition.

12 . Mesoporous CuO prepared according to the method of claim 10 .
