Accordingh to various studies Nitrogen Doped Graphene is a better catalyst for electrolysis than platinum.
I will be coating some carbon fiber electrodes with nitrogen doped graphene quantum dots and a binder material most likely PVDF or PVP. GO quantum dots are prepared by oxidizing graphite/graphene, and treating with ultrasonication to continue to break the graphene oxide into smaller and smaller pieces.
Using urea and a microwave the oxygen groups can then be replaced with nitrogen and annealing/reduction with l-ascorbic acid to close the five membered rings containing nitrogen.
The two control groups will be using pristine carbon fiber electrodes of equal weight to the CF electrodes coated with n-doped graphene quantum dots and n doped multiwalled carbon nanotubes.
These will be placed in a simple hoffman apparatus and the mWh will be compared to volume of evolved gasses to determine efficiency.
Moving forward I would like to try ultrasonication in conjunction to see if there can be further increases in effeciency. This will probably only work on a much larger scale but I will see.
