This study provides a description of a simplified, accelerated and economically advantageous method for determining the catalytic activity of carbon compounds based on graphene oxide (GO) and graphitic carbon nitride g-C3N4 during the electrolysis of water. The method proposed in this study for determining the catalytic activity of carbon compounds based on graphene oxide and graphitic carbon nitride is based on measuring the amount of H2 bubbles formed by the process of the dissociation of water on a cathode. A swarm of rising bubbles indicated the effectiveness of the catalysts. The principle of the proposed method for determining catalytic activity is based on measuring changes in the intensity of light illuminating the cathode. Such changes are influenced by the amount of bubbles formed. The experiments confirmed that the nanostructures employed enhanced reactivity and provided support for the photocatalytic reactions involved in the production of hydrogen.
