摘要：
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.
