NOVELTY - Method for obtaining the graphene/iron(II) chromate composite, involves sonicating 0.5 g graphene oxide in 50 ml ethanol, adding iron nitrate and chromium nitrate in a ratio of 1:1 to the solution, adding 25% aqueous ammonia solution, pressurizing the mixture in a solvothermal microwave reactor for 15-45 minutes at a pressure of 4-6 MPa, subjecting the resulting product to an annealing process in an inert atmosphere at a temperature of 500-650 degrees C, and drying and rinsing with distilled water, where the mixture is subjected to pressure treatment in an autoclave at a temperature of 120-200 degrees C for 12-20 hours. USE - The method is used for obtaining the graphene/iron(II) chromate composite.
