Latest Patents

Ji-Hyun Jang's latest patents include a bismuth vanadate electrode comprising vanadium-functionalized graphene quantum dots and a preparation method thereof. This invention discloses a bismuth vanadate electrode that incorporates vanadium-functionalized graphene quantum dots. The method involves immersing a bismuth vanadate (BiVO) electrode in an alkaline solution to remove excess vanadium oxide (VO) formed during preparation. The addition of graphene quantum dots (GQDs) protects the electrode from the alkaline solution, as they are adsorbed onto the surface of BiVO while VO is removed. This innovative approach significantly improves the efficiency of the oxygen evolution reaction (OER) when applied to a photoanode.
