P-Doped Graphene Obtained by Pyrolysis of Modified Alginate as a Photocatalyst for Hydrogen Generation from Water-Methanol Mixtures

The right dope: Phosphorus‐doped graphene was obtained by the pyrolysis of natural alginate that contained H2PO4− at 900 °C. This material catalyzes the generation of H2 from a water/methanol mixture upon irradiation with UV or visible light. An increase in the amount of H2PO4− leads to a higher pho...

Description
Summary:The right dope: Phosphorus‐doped graphene was obtained by the pyrolysis of natural alginate that contained H2PO4− at 900 °C. This material catalyzes the generation of H2 from a water/methanol mixture upon irradiation with UV or visible light. An increase in the amount of H2PO4− leads to a higher photocatalytic activity.
