Abstract
Disclosed are a catalyst composite including a metal; and a nitrogen-containing porous 2D polymer carrier, and a method of manufacturing the catalyst composite. Accordingly, provided is a high-efficiency catalyst composite that does not depend on pH acid concentration using a nitrogen-containing porous two-dimensional (2D) polymer carrier and a low-cost metal.
Claims15
A catalyst composite comprising:
- (i)ruthenium (Ru);
- (ii) at least one selected from the group consisting of cerium (Ce), iron (Fe), rhodium (Rh), palladium (Pd), cobalt (Co), nickel (Ni), gold (Au), silver (Ag), manganese (Mn), zinc (Zn), copper (Cu), and molybdenum (Mo);
- and
- (iii) a nitrogen-containing porous two-dimensional (2D) polymer carrier;
- wherein a ratio of the ruthenium to all other metal is a molar ratio of 1:0.01 to 1:0.5;
- and
- wherein the nitrogen-containing porous two-dimensional (2D) polymer carrier comprises six aromatic rings arranged to form a hole and a diameter of the hole is 0.1 nm to 10 nm.
