Aqueous phase reforming of glycerol using doped graphenes as metal-free catalysts

Abstract

Boron-doped graphene obtained by pyrolysis at 900 oC of the boric acid ester of alginate was found the most active graphene among a series of doped and co-doped graphenes to promote the aqueous phase reforming of glycerol at 250 oC. This reaction is of interest in the context of valorization of aqueous wastes of carbohydrate syrups. Control experiments adding to undoped graphene 1 wt. % of triphenylborane, tris(pentafluorophenyl)borane or bis(pinacolyl)diborane as models of the two possible boron atom types present in B-doped graphene, and boric acid that could be present in a residual amount after pyrolisis, show in all cases an increase in the catalytic activity of graphene. B-doped graphene has also activity for glucose aqueous phase reforming. The results show that graphenes are promising metal-free catalysts for aqueous phase reforming alternative to those containing platinum.
