NOVELTY - Process for the production of porous N-graphene doped with nitrogen atoms, involves: (a) adding 0.2-0.4 g polyallylamine hydrochloride in 100 ml of water in a container and adjust its pH value to 6-9 by adding a potassium hydroxide solution; (b) adding 1-3 g graphite oxide (GO) in 250-750 ml distilled water; (c) exfoliating the GO dispersion and then centrifuge at 3000-7000 rpm for 20-60 minutes; (d) adding the polyallylamine solution to the dispersion and keep the mixture obtained under agitation of 500-2000 rpm for 2-4 hours; (e) transferring the mixture to an autoclave at a temperature of 80-150° C for 10-14 hours and obtain the intermediate product; (f) mixing 0.4-0.8 g intermediate product with 3.6-7.2 g of potassium hydroxide in 50 ml solvent; (g) introducing the solid into a quartz tube in a vertical oven, of 24-800° C and under a nitrogen flow; (h) cooling the solid to room temperature; and (i) washing the solid with distilled water with 4-7 washes until reaching pH of 6-8. USE - The process is used for producing porous n-graphene doped with nitrogen atoms, where the n-graphene is used for the separation and capture of carbon dioxide and storage of hydrogen gas, from emissions from anthropogenic sources. ADVANTAGE - The process produces porous n-graphene doped with nitrogen atoms that has a high capacity to adsorb gases. The graphene is a low cost of regeneration of the material. The n-graphene doped with nitrogen atoms captures carbon dioxide or stores hydrogen that does not present the formation of products harmful to health or the environment, and is able to be regenerated at room temperature, using only a vacuum. DETAILED DESCRIPTION - Process for the production of porous N-graphene doped with nitrogen atoms, involves: (a) adding 0.2-0.4 g polyallylamine hydrochloride (PAA) in 100 ml of water in a container and adjust its pH value to 6-9 by adding a potassium hydroxide solution with concentration 1 mol/l; (b) adding 1-3 g graphite oxide (GO) in 250-750 ml distilled water in an additional container; (c) exfoliating the GO dispersion from step (b) in an ultrasound bath at ultrasonic power of 100-200 Watts for 1-4 hours and then centrifuge at 3000-7000 rpm for 20-60 minutes and keep under magnetic stirring of 500-2000 rpm; (d) adding the polyallylamine solution from step (a) to the dispersion in step (c) at a volumetric flow rate of 0.1-1 ml/minute and keep the mixture obtained under agitation of 500-2000 rpm for 2-4 hours; (e) transferring the mixture to an autoclave at a temperature of 80-150° C for 10-14 hours and obtain the intermediate product; (f) mixing 0.4-0.8 g intermediate product with 3.6-7.2 g of potassium hydroxide in 50 ml solvent, keep under magnetic stirring of 1000-5000 rpm and 50-100° C, until the complete evaporation of the solvent; (g) introducing the solid resulting from step (f) into a quartz tube in a vertical oven, of 24-800° C and under a nitrogen flow with a flow rate of 50 ml/minute and a heating rate of 5-10° C/minutes for 1-2 hours; (h) cooling the solid to room temperature; and (i) washing the solid with distilled water with 4-7 washes until reaching pH of 6-8. An INDEPENDENT CLAIM is included for the N-graphene, obtained by the process, comprising 7-9 wt.% nitrogen atoms, 68-74 wt.% carbon atoms and 18-24 wt.% oxygen atoms.
