Inhaltsangabe

The method presented in this publication is used to determine the catalytic activity of carbon-based compounds derived from graphene oxide and graphitic carbon nitride. It is based on measuring the volume of H2 bubbles generated during water dissociation at the cathode, where the extent of the bubble swarm directly correlates with photocatalytic efficiency. A green LED is used to illuminate the bubble swarm, with a light intensity sensor positioned on the same axis as the light source and the cathode. The measured changes in light intensity are then captured, recorded, evaluated, and expressed graphically.
