a metallic nickel body; and
a plurality of microstructures connected to the metallic nickel body on at least one surface of the metallic nickel body;
wherein the microstructures are sharp, and have a length-diameter ratio ranging from 2 to 5.

2. The nano-nickel catalyst according to claim 1 , wherein the microstructures contain metallic nickel.

3. The nano-nickel catalyst according to claim 2 , wherein the microstructures are made of metallic nickel.

4. The nano-nickel catalyst according to claim 1 , wherein the metallic nickel body is spherical.

5. The nano-nickel catalyst according to claim 1 , wherein the metallic nickel body is porous.

6. The nano-nickel catalyst according to claim 5 , wherein the metallic nickel body is porous, and has an adsorption pore volume ranging from 0.0024 cm 3 /g to 0.0062 cm 3 /g.

7. The nano-nickel catalyst according to claim 1 , wherein the metallic nickel body is solid.

8. The nano-nickel catalyst according to claim 1 , wherein the metallic nickel body is hollow.

9. The nano-nickel catalyst according to claim 1 , wherein the nano-nickel catalyst has a specific surface area ranging from 1.5 m 2 /g to 2.0 m 2 /g.

10. The nano-nickel catalyst according to claim 1 , wherein the nano-nickel catalyst has an ability to reduce carbon dioxide into low-carbon hydrocarbons.

11. The nano-nickel catalyst according to claim 10 , wherein the low-carbon hydrocarbons are selected from a group consisting of methane, ethane, propane, and a combination thereof.

12. A hydrogenation device of carbon oxides, comprising:
a first reactor having a first catalyst bed therein; and
a second reactor having a second catalyst bed therein, and communicated with the first reactor through a channel;
wherein the first catalyst bed and the second catalyst bed both comprise a nano-nickel catalyst according to claim 1 .

13. The hydrogenation device of carbon oxides according to claim 12 , wherein the first catalyst bed has a first catalyst fill rate with a minimum value of 0.3 g/ml, and the second catalyst bed has a second catalyst fill rate with a minimum value of 0.15 g/ml.
