Abstract

A method can include incorporating graphene oxide (GO) in a solution, reducing the graphene oxide (GO) by refluxing carbon nitride (C 3 N 4 ) in the solution to form carbon-nitride refluxed-graphene-oxide (C 3 N 4 -rGO) composites, and incorporating ruthenium ions into the C 3 N 4 -rGO composites to form C 3 N 4 -rGO-Ru complexes.

Claims (13)

1. A material including C 3 N 4 -rGO-Ru complexes produced by a method comprising:

incorporating graphene oxide (GO) in a solution;

reducing the graphene oxide (GO) by refluxing carbon nitride (C 3 N 4 ) in the solution to form carbon-nitride refluxed-graphene-oxide (C 3 N 4 -rGO) composites; and

incorporating ruthenium ions into the C 3 N 4 -rGO composites to form the C 3 N 4 -rGO-Ru complexes.

2. The material of claim 1 , wherein the method further comprises using the C 3 N 4 -rGO-Ru complexes as a catalyst in a hydrogen evolution reaction (HER) process.

3. The material of claim 1 , wherein the method further comprises assembling C 3 N 4 sheets onto the refluxed GO to form a sandwich structure.

4. The material of claim 1 , wherein the reducing includes using ascorbic acid in the solution.

5. The material of claim 1 , wherein the incorporating includes refluxing ruthenium chloride (RuCl 3 ) in the solution.

6. The material of claim 1 , wherein the method further comprises confirming the formed C 3 N 4 -rGO composites by atomic force microscope (AFM) measurements.

7. The material of claim 1 , wherein the method further comprises performing x-ray photoelectron spectroscopic (XPS) measurements on the C 3 N 4 -rGO-Ru complexes.

8. The material of claim 1 , wherein the method further comprises performing transmission electron microscopy (TEM) on the C 3 N 4 -rGO-Ru complexes.

9. The material of claim 1 , wherein the solution is an aqueous solution.

10. The material of claim 9 , wherein the aqueous solution is water.
