New technique converts eggshells into bulky nanoporous graphene and pure hydrogen

A recent study, affiliated with UNIST has unveiled a new way to turn discarded eggshells into hydrogen, an innovative and alternative energy for the future. The new method, which is used as a catalyst for the conversion of alcohols to hydrogen, is used for the synthesis of graphene on the shell after the reaction. This technique of producing value‐added graphene and pure hydrogen, while recycling food waste is a way to "kill three birds with one stone."
